Emergent projects

Most research funding schemes focus on projects of excellence based on a set of deliverables.  This context makes more and more difficult to explore intrinsically risky research routes.

To compensate for this “lack”, ISITE-BFC provides support for original, innovative and risky scientific projects that are likely to advance scientific knowledge in various fields, including those that do not depend on the 3 priority axis defined in Bourgogne-Franche-Comté.

Along the same line, ISITE-BFC encourages interdisciplinary research. The objective is to create permanently cross-fertilization opportunities of two types: across the three strategic priority areas and across other scientific fields.

1st AXIS

IQUINS (Integrated Quantum Information at the Nanoscale) aims at developping new techniques of quantum information processing in order to integrate them at the nanoscale, typically via quantum plasmonics and the realization of an advanced integrated photonic plateform. Conducted by a pluridisciplinary team of 18 researchers from 5 laboratories (ICB, FEMTO-ST, UTINAM, IMB, LMB) and on three sites (Belfort-Besançon-Dijon) of UBFC, the second objective of the project is the emergence of a highly visible UBFC Quantum Information group. To achieve the scientific objectives of the projet and to create a Quantum Information community, three topics have been identified in the project:

  • The geometry of quantum computation (studying entanglement and quantum contextuality),
  • Quantum control (developping a theoretical framework for nanostructured environnements),
  • Integrated systems (producing integrated single photon sources).

Nanotechnologies is a fastly growing field from both industrial and scientific point of views. The recent emergence of many innovative materials and nano-objects with outstanding characteristics goes with the need to study them and also to combine them to form more complex arrangements such as NEMS, nano-sensors or nano-optical devices. Among existing characterization to manufacturing techniques (self-assembly, chemical synthesis, electron beam lithography, mobile nanoparticules…), the use of nanorobotic platforms recently demonstrate extremely high interest through achieving, in an original way, nanomanipulation and nano-assembly tasks offering disruptive characterization and nanomanufacturing potential. Nevertheless, these nanorobots rely on tools initially developed for microscopy or microscale robotics purposes that have been derived for nanorobotics tasks. Then, intrinsic limitations induce numerous remaining issues to overcome the need of resolution and precision and also dexterity and control of multi-Degrees-of-Freedom trajectories.
Based on FEMTO-ST expertise for miniaturized robotics, the NANOFACTORY project aims at developing a new generation of nanorobot able to achieve highly performing tasks with high repeatability for nanoscale characterization, prototyping of novel nanotechnologies up to the manufacturing of new hybrid or assembled nanodevices.
The basic concepts of this disruptive nanorobot generation relies on complex spatial and automated motions in a versatile and ease of use manner at the nanoscale. A new class of parallel continuum microrobots is notably being investigated and first results already demonstrated the capability to provide extremely high manipulation ability and high accuracy (better than 10 nm is targeted). Original vision based algorithm providing multiple Degrees-of-Freedom measurement with wide range to resolution ratio also enabled to achieve very high positioning accuracy tasks within a Scanning Electron Microscope. Works notably conducted to achieve several and efficient Carbon Nanotubes manipulation tasks in a unique and accurate way conducting to original and disruptive ways of analysing properties.

An innovative trend promoted by the unique capabilities of additive manufacturing techniques is about the “4D Printing” concept. It is actually the process by which assemblies and parts embodying smart materials are printed, they are therefore able to react to changes in their environment. As a new way of thinking and manufacturing method, few is known about how to systematically bring such smart products ideas into reality. This HERMES research proposal aims at introducing a general framework for designing 4D printed solutions. It delineates the research effort to be made so that designers are sufficiently empowered to design such smart products. For this reason, the HERMES project proposal aims at elaborating (i) a strong foundational theory enough suitable for covering the semantic and logical description of dynamical phenomena knowledge at various scales (i.e. territory/building, mechanical assembly, material, etc.), (ii) a multi-layer ontology for semantic and logical reasoning, on which (iii) computational mechanisms will be developed in order to deliver dynamical CAD models ready for 4D printing. All these objectives present cutting edges efforts from a logical and semantic point of view as well as from a procedural perspective, and will be achieved via an original collaboration connecting fields of mechanical engineering, material engineering, artificial intelligence and geoinformatics. The ultimate goal of HERMES is to extend current CAD systems capabilities to fully embrace 4D printing opportunities and the increase of reasoning capacities embedded in systems and matter.

The field of photonics is one of the fastest growing research areas in modern science, with direct and almost-immediate impact on the development of new industries. Important examples of new fibre-based technologies include supercontinuum (SC) broadband light sources. They provide a broadband light spectrum with the brightness of a laser and the spectral width of a lamp, effectively replacing most of light sources used today in optical metrology, spectroscopy, and bio-photonics. These sources are being developed and marketed by several companies, ALPhANOV, Leukos, Novae in France and NKT Photonics in Denmark. The advent of the photonic crystal fibres (PCFs) has also led to revolutionary advances in photonics and laser technologies, particularly relating to the process of SC generation. State-of-the-art SC lasers are based on silica PCFs providing watts of output power over the bandwidth 400-nm-2.2 µm, or fluoride fibres with several mW of power between 1and 4 µm. However, many industrial applications such as detection of chemical and biological species would benefit from extending the SC spectrum beyond the state of the art, towards the ultraviolet (UV) and the mid-infrared (IR) range.

The key goal of SCUVIRA project is to build, on this current state-of-the-art, the next generation of SC fibre-based sources in the mid-IR (1-15 µm) and UV (200-400 nm) ranges with characteristics tailored to end-user driven applications such as optical detection, spectroscopy, gas and chemical sensing, fluorescence imaging. SCUVIRA will built on the knowledge and complementary of two research groups of the I-SITE UBFC program, ICB in Dijon and Femto-ST in Besançon. We aim in particular to design and draw new highly nonlinear fibres based on IR tellurite (TeO2) and chalcogenide (As-free selenium based) glasses and to demonstrate with these fibres wideband mid-IR SC generation up to 5 µm for tellurite glasses and 15 µm with chalcogenide glasses. On the other hand, UV SC generation will be achieved by use of specialty UV silica-based PCFs with an adapted composition allowing the suppression of the UV absorption issue.

The project CoILS (Colloidal Integrated Light Sources) aimed at developing Nanoplatelets (NPls) based colloidal quantum emitter integrated light sources for low cost active opto-chips. The colloidal light sources are expected to be a strategic low cost alternative to technologically demanding integrated light emitting diodes.

In the context of colloidal integrated light sources, Nano-platelet emitters are of key interest compared to standard spherical quantum dots. Indeed, beyond their unique fluorescence performances, Nano-platelets feature auto assembly properties and dipole orientation of critical importance for a controlled deposition and emission of the fluorescent sources.

As a proof of principle, the light sources will be deployed in a functional refractive index sensor for liquid. To this aim, colloidal light sources featuring a broad enough emission spectrum will be integrated to achieve the excitation of micro-disks or micro-rings resonators. Up to several hundredths of resonators will be excited simultaneously by using a simple collimated pump beam. This specific optical pumping configuration can be achieved with no need of tedious and time consuming optical alignments that are generally needed whenever an integrated optics configuration is operated. By using those colloidal integrated light sources, we will demonstrate a highly parallel, optical alignment-free optical sensor.

Beyond the simple fluorescent light sources for optical sensors, we will address in CoILS advanced emission properties of the NPls such as amplified spontaneous emission (ASE) or even Lasing opening the way toward appealing topics such as colloidal nanoplatelets for visible optical on-hip communications.

Knowledge of the current density distribution inside the Fuel Cell can indicate an abnormal operation and thus offer an effective diagnosis approach. The magnetotomography is the only noninvasive current density mapping method based on the measurement of the external magnetic field surrounding the stack. Recent work at FEMTO-ST/FCLAB developed a new FC stack magnetic field measurement methodology essentially different in comparison with other methodologies proposed until now. This new approach makes possible a more accurate analysis of the current distribution inside the Fuel Cell. This project aims to:

  • develop diagnosis procedures and current mapping methods for detecting default cell operation inside the volume of the FC stack based on the new methodology,
  • take into consideration magnetic 3D effects to improve the existent test bench,
  • validate the new measurement system and methodology on a real fuel cell stack.

The purpose of SWO is to open new perspectives for Brillouin (SBS) and Raman (SRS) effects in integrated photonics. The project relies on the exploitation of engineered mechanical resonances (EMRs) that are controlled through nanostructuration and that act as synthetic analogues to the natural SRS/SBS effects. Compared to standard studies which are restricted to low frequency (<<100 MHz for the Raman-like effect, ~10GHz for SBS) and small bandwidth (<1MHz), the originality of SWO project lies in the aim for the highest possible mechanical frequencies, 50GHz and above.

In order to succeed, substantial changes to the current approach must be performed. Especially the use of electronics means for studying experimentally cavity optomechanics (<100MHz) or SBS effects (~10GHz) is not adapted to the investigation of higher frequencies and the peculiar phase-matching properties they could have; therefore a specific all-optical characterization experiment must be developed.

At the level of fundamental science, SWO will result in a better understanding of photon-phonon interaction in semi-conductor photonic integrated chips (PICs). Indeed, by gradually pushing forward optomechanics to its frequency limits, different classes of mechanical vibrations from bulk acoustic resonances up to Surface Acoustic Waves (SWOs) will be investigated.

Near-infrared (NIR) fluorescent organic dyes are attractive molecular tools for biosensing/bioimaging because the benefits they provide in biological contexts are numerous and include a large gain of sensitivity (i.e., directly linked to low background fluorescence in the therapeutic window of 700-900 nm), a marked safety profile compared to dyes absorbing at more energetic wavelengths, and deeper tissue penetration. Despite of considerable amount of relevant achievements in the field of such photoactive organic molecules, some issues related to their facile synthetic accessibility/tunability, (photo)chemical stability, biocompatibility and fluorogenic reactivity remain to be addressed for high-tech applications. The goal of this project is to explore a unique approach toward tunable NIR fluorophores based on unprecedented BacterioChlorin-DiketoPyrroloPyrrole (BC-DPP) hybrid core structures. Our guiding idea is to take advantage of valuable inherent properties of natural chlorophyll-related hydroporphyrins (strong absorption/emission within the therapeutic window and assumed inherent biocompatibility) and to impart to them additional features without resorting to tedious de novo syntheses generally required to access to these porphyrin-like molecules. To achieve this, we will explore different chromophore merging-based strategies leading to covalent association between BC and DPP units, and taking advantage of facile synthesis, versatility and outstanding properties of DPP scaffold. To highlight performances of these novel NIR fluorophores and to demonstrate their potential utility, application in the field of diagnostic microbiology will be regarded. “Turn-on” fluorogenic probes suitable for visualizing microbiological enzymes in pathogenic bacteria and yeasts in real-time will be designed from the most promising candidates. Possible benefits of these unusual enzymatic substrates in phenotypic bacterial identification will be assessed.

Dispersive partial differential equations (PDEs) have important applications in different research areas such as hydrodynamics, optics, plasma physics and medical imaging. In this project these PDEs, including in higher dimensions, will be studied with a unique innovative combination of analytical and numerical approaches and techniques from the theory of integrable systems, also applied to non-integrable PDEs. The goal is to use the predictive power of numerical techniques for breakthroughs on the analytical side, and analytical insight into the equations to generate innovative numerical schemes able to address challenges in applications numerically. In particular we intend to study exact solutions to these equations as solitons and breathers and their stability, the appearance of dispersive shock waves (zones of rapid modulated oscillations in the solutions), blow-up (a loss of regularity in the solutions) and inverse scattering approaches to integrable PDEs in higher dimensions.

The raise of environmental and economical concerns resulted in a search for materials featuring multi-functionalities and fulfilling conflicting needs. This project targets one possible innovative route, by developing geometries and material gradients at scales which are comparable with the scale of the component. As such, this project lies within the scope of the flourishing field of ‘architectured materials’ which blur the classical separation between ‘materials ‘and ‘structures’. Yet, even though linking the properties at the elementary scale to the derived functionalities at the material scale in this context of weak scale separation has received a lot of (theoretical) attention, the experimental implementation and validation of this scale transition in architectured materials remain extremely limited in the literature. The ambition of this project is thus to experimentally assess this scale transition and to check for the controllability of the properties of key architectured materials in various contexts.
The experimental approach is thus to tailor full-field measurement tools to architectured materials and to apply these to the static and dynamic multi-scale study of macroscopic, well-controlled, materials. The obtained know-how and knowledge will then be re-invested in the much more challenging characterization of the scale relations involved in the dynamic behavior of networks of micrometer-scaled resonators. These new key knowledge and know-how are expected to pave the way for innovative products.

This project aims to explore the capabilities of digital holography coupled with digital photogrammetry to perform sub-pixel sample positioning measurements in microrobotics and photonics. A key novelty of the project will be to include an Artificial Intelligence (AI) dimension through machine learning approaches harnessing Artificial Neural Network (ANN) architectures intensively studied in computer vision and imaging. The most well-known subclasses of these architectures are feedforward ANN – Deep-Learningbased methods- such as Convolutional Neural Networks (CNN), widely applied to computer vision and image processing. However, while Deep Learning has become the most exploited technique in recent years, other ANN approaches, such as Recurrent Neural Network (RNN) and Reservoir Computing (RC) offer very promising alternative configurations because they can use their internal dynamics to mimic a memory-like behavior and to process a temporal sequence of input data to retain information from a previous state. RNN and RC are especially well-suited for data analysis and prediction and represent solutions for hardware implementation of ANN. This project has the specific aim of using these approaches to accelerate the determination of the various unknown metrics of an often complex imaging device in microrobotics and photonics. Applications such as 3D position measurement at micro scale of micro-objects and surface roughness measurement of fluoride crystals in mm-size WGM resonators to target real time applications in an extended workspace will be addressed in the proposed project.
The particular challenge will be to perform complex dynamic data predictions available from a sequence of digital holograms recorded on a 2D CMOS sensor. This project builds on the recent renewed interest in ANN that has spread to various scientific communities ranging from neuroscience to physics, and thus strongly promotes cross-disciplinarity.

Grasslands support Protected Designation of Origin (PDO) dairy production systems. Their important biodiversity is a key component of the “terroir”, responsible for product specificity. For a sustainable development of PDO dairy production, ecological intensification of grassland use is a major challenge, particularly through optimal fertilization. A major concern is the impact of fertilizers (quantity and quality) on grassland biodiversity and on the link of the product to its terroir. Taking the PDO Comté cheese as a case study, IFEP will evaluate the impacts of fertilization practices (farmyard manure, slurry) on dairy production sustainability by an approach associating environmental quality of grassland ecosystems and the fluxes of useful microorganisms (“terroir effect”) and chemical contaminants from environment to milk. This innovative approach will help to better understand the determinants of PDO products specificity and to define optimal fertilization specifications for sustainable grassland management preserving cheese specificity and quality as well as ecosystem health.

Obesity, a major cause of disability and mortality, continues to strain on the French Health system. One cause of this societal issue is certainly our poor knowledge of the disease mechanisms. Recent genetic studies formally implicate the brain in obesity pathology and pinpoint genes regulating synaptic plasticity. Rodent data consistently evidence synaptic plasticity in brain circuits controlling appetite. Our lab with strong expertise in neuroscience and physiology aims at identifying the value of this state-dependent plasticity within brain feeding circuits. High-resolution imaging and modern neuroscience research tools will be leveraged to elucidate how food is integrated in discrete ‘soft’ circuits at the meal scale. Behavioral effects of meal-related changes in synaptic connection and neuroglial interaction will be fully examined. Such new knowledge about intimate mechanisms of satiety might provide new ways to manage obesity and maladaptive eating behaviors.

The islands have the advantage of being geographically well defined spaces, possessing their own particular ecosystems and well definable network of sites and landscape marks. The IATEKA project propose the region of the Kvarner archipelago situated in the northern Adriatic (Croatia) as its case-study region. These islands are the subject of historical and archaeological research focused on the territories of the site of Mirine-Fulfinum (Krk), occupied between 1st and 8th c. AD, and of the city of Osor (Cres), which has been experiencing uninterrupted occupation since the protohistoric oppidum to the present day.

Historical and archaeological data, which will determine the major stages of the population settlement and the variability of the occupations, will be associated with information provided by anthropology which will specify the origin of the populations, their living conditions, and their diet. The palaeoenvironmental analysis will determine the natural setting of successive human occupations. The evolution of the vegetation cover and the dynamics of the sedimentary flows will be apprehended from the study of the available sedimentary recordings and will make it possible to specify the main eco-geo-systemic responses to the climatic changes, the development of the resources and the impact of agricultural practices. The spatial archaeology analysis will complete this information by specifying the different stages of structuring the territories of these islands.

The purpose of this approach is to search for signals to describe the main lines of population evolution and their consequences on the evolution of these island environments. By multiplying the markers (anthropology, isotopes, pollens, micro-fossils, micro-coals, chironomes, diatoms, geochemical and geophysical signals, data of space archaeology and regressive analysis of landscapes, etc.), we will be able to better apprehend the structuring of the current territory.

Eating behaviour is a key determinant of human health and inappropriate behaviours can be at the origin of some of the major pathologies affecting the modern societies (obesity, cardiovascular diseases, diabetes). Among the biological factors known to influence eating behaviour, sensory perception (including the sense of taste) plays an important role. Taste perception varies strongly between individuals but the factors at the origin of this variability are not fully understood. For example, different events occurring at the vicinity of the taste receptors on the tongue could modulate taste perception. Our group has recently suggested that the microbiota at the surface of the tongue could be involved by controlling the taste compounds concentration in the lingual film (the biological material covering the tongue). The aim of this project is to evaluate the contribution of the oral (lingual) microbiota in taste. The project will consist first in the determination of taste sensitivity (5 basic tastes) in 100 healthy adult subjects and the characterization of their lingual film in terms of microbiota (metagenomics) and metabolites (HPLC). Using these data, a second step will consist in identifying bacterial species and metabolites linked to taste sensitivity. A final step will focus on modelling the metabolites concentration at the vicinity of the taste receptors taking into account the diffusional constraints and microenvironments of the lingual film.

The ambition of this proof of concept project is to document the involvement of oral microbiota in taste. This approach would constitute a breakthrough in consolidating the knowledge related to the sense of taste, a major physiological function involved in food consumption and enjoyment. This would strengthen the expertise of Dijon and the Bourgogne Franche-Comté region in the food and nutrition related sciences.

Nitric oxide (NO) is a ubiquitous biological signalling molecule involved in numerous plant physiological processes including immunity. We recently demonstrated that Nitric Oxide Synthase (NOSs), the major enzymatic sources of NO in animals which are also present in other organisms including prokaryotes, are absent from land plants but conserved in some classes of green algae. Our preliminary data indicate that algae NOSs form a new family of proteins with singular structural and functional features. By combining biochemical, biophysical, cellular and physiological approaches, we aim at deciphering the structural and enzymatic properties as well as investigating the regulation and physiological roles of the NOS of the alga Klebsormidium flaccidum and Cosmarium subtumidum. K. flaccidum is a filamentous terrestrial alga used as a biological model to elucidate the early transition step from aquatic algae to land plants. C. subtumidum is a freshwater species possessing a NOS displaying unexpected structural features. The role of these NOSs as well as their enzymatic products (mainly NO) in algae growth, innate immunity and responses to abiotic stresses will be particularly analyzed through the identification of their protein partners and of proteins undergoing S-nitrosylation, a NO-dependent post-translational protein modification. Overall, this project will provide original information on the structure/function, regulation and biological roles of new NOSs, will expand our knowledge of algae physiology and will contribute to a better understanding of the evolution of redox signaling and its role in the emergence of immunity.

The possibility that climate change exacerbates the impact of invasive species at the expense of native ones is of major concern for Conservation biologists. Due to their limited ability as ectotherms to regulate body temperature above or below ambient, invertebrates can be particularly affected by the variation of temperature in their environment. In this context, we propose to develop a multidisciplinary approach to examine the impact of increased temperature and temperature variability (supposed to pose a greater risk to species than climate warming) on two invertebrate invading species in Burgundy, the spotted wing fly, Drosophila suzukii and the freshwater crustacean amphipod, Gammarus roeseli, and their “rival” native species D. melanogaster and G. fossarum. More specifically, we wish to answer two questions: 1) Do behavioural, physiological and life-history traits of invasive and native species vary according to mean temperature and temperature variability? and 2) Are increased temperatures and temperature variability likely to affect the competition between D. suzukii and G. roeseli and native congeneric species in Burgundy? The first question will be addressed through focusing on a suite of traits of particular evolutionary and ecological relevance, including foraging behaviour, reproductive behaviour, personality and behavioural flexibility, developmental instability and homeostasis, and physiological markers of thermal stress. The second question will be answered through examining the outcome of competition between congeneric invasive and native species under different temperature regimes in cage populations and microcosms. This project is of major relevance to current environmental issues in Burgundy and will be beneficial for development of a new academic training in behavioural ecology and wildlife management at the master level at the Université de Bourgogne-Franche Comté.

In   a   context   of   societal   concern   about   food   and   wine   conservation,   which   implies   low   input, environmental    friendly    production    styles    and    innovation    for    economical    breakthroughs,    the understanding  of  the  mechanisms  involved  in  the  chemistry  of  preservatives  like  sulfites  is  crucial. Although  alternatives  such  as  glutathione  have  shown  great  potential,  sulfites  remain  unavoidable  for various processed foods, and for wine in particular. Wine constitutes a challenging example where several attempts  were  made  to  find  alternatives,  but  none  of  them  could  exhibit  the  expected  efficiency  for preserving  wine  from  autoxidation  during  bottle  ageing.  However,  due  to  health  aspects,  there  are growing  discussions  about  the  reduction  and  possibly  the  banning  of  sulfites.  Besides,  wine  constitutes another   challenge   associated   with   a   worldwide   observed   premature   oxidation   of   white   wines   in particular. Although such oxidized state has been rather well described after the identification of volatile markers such as aldehydes or lactones, or with the colour browning, transient mechanisms responsible for that remain poorly understood. Therefore, this project aims at developing innovative analytical tools for a better understanding and monitoring of white wine’s antioxidant chemistry through combined controlled oxidation  procedures  and  metabolomics  analyses  of  the  reactional  activity  of  well  known  (glutathione, sulfites), and possible alternative natural antioxidants. Our project relies on the ability of metabolomics to manage  transient  chemical  interplays  in  complex  biological  matrices  and  under  controlled  oxidation states,  and  should  pave  the  way  for  the  development  of  efficient  strategies  for  the  future  discovery  of innovative   preservative.   As   a   unique   beverage,   wine   will   be   considered   here   as   an   emblematic representative of oxidation-­‐sensitive matrices, conveyor of universally shared science and knowledge.

Autophagy is a critical regulator of cell homeostasis and metabolism, whose regulation is highly sensitive to nutritional variations, including those in lipids. It has a well-recognized role in maintaining the structure and function of the retina. A decline of autophagy activity is observed during physiological aging of the retina and in age-related macular degeneration (AMD), the primary cause of blindness in industrialized countries. The retina is particularly sensitive to dietary lipid variations. Studies have shown the deleterious effects of Western diet (diet with excessive levels of omega-6 polyunsaturated fatty acids (PUFA) but very low levels of omega-3 PUFA) and the benefits provided by omega-3 PUFA in AMD.

Our objectives are to study whether the relative proportion in which dietary omega-6 and omega-3 PUFA are consumed and the nature of dietary omega-3 PUFA have an impact on the decline of autophagy during aging and the appearance/progression of signs of aging in the retina. Functionality of the retina, autophagy, aging and fatty acid will be analyzed during aging in retinas of mice that followed specific diets.

This project will generate innovative fundamental data on the impact of the ratio and the nature of dietary omega-6 and omega-3 PUFA (i) on aging of the retina (“well aging” vs “pathological aging”), and (ii) on the activity of autophagy in the retina during aging. It will determine whether a high omega-6:omega-3 ratio, as found in today’s Western diet, is a factor favoring/causing the decline of autophagy and aging of the retina. This project will also bring an in vivo evaluation of the recommendations made by health agencies on the omega-6:omega-3 ratio and keys regarding the importance of the nature of omega-3 PUFA brought by the diet. Finally, it will evaluate the in vivo potential of omega-3 fatty acids as nutritional inducers of autophagy, which could have applications in wide range of diseases linked to autophagy defects.

The aim of this project is to design a “smart” packaging able to inform the consumer or the retailer about the quality and freshness of a food in real time. The approach that will be implemented for the development of these packaging is highly original and innovative. It is based on the interaction between a food quality marker and a molecularly imprinted polymer that will be included in the packaging. This work will consist in designing these new polymers for selectively capturing oxidative markers from food. Then, they will be coupled to a probe capable of changing its light transmission properties following interaction with the quality marker in contact with the packaged food. Such change will inform the consumer or the retailer about the quality of the food product. Before testing on food products the safety of the system as a food contact material will be critically assessed. This project is thus at the interface of several current problems facing the agri‐food industry: the fight
against food waste, the guarantee of healthy food products and the development of intelligent systems capable of informing the consumer.
All complementary skills within a research team (UMR PAM) and in collaboration with two other research teams (UMR LNC, URTAL) will be gathered for this innovative project, from the synthesis of new molecularly imprinted polymers to the design of safe and intelligent packaging and application to food products.

Biodiversity includes complex systems of interacting species providing goods and services of value to human societies. Anthropogenic land-use changes are the primary cause of biodiversity erosion as they are associated with the decline and extinction of numerous species. However, we know much less how habitat modifications affect the structure and the functioning of whole interacting communities, despite the link between ecological network properties and s ecosystems stability. Using a unified conceptual and methodological framework based on graph theory and network analyses, the present project aims at understanding how tropical forest loss and fragmentation affect the structure and the functioning of antagonist host-parasite interactions. We use birds and their haemosporidian blood parasites (Plasmodium and Haemoproteus) as a biological model. This project explores the underlying mechanisms by focusing on how and to what extent habitat loss and fragmentation shape both structural (spatial networks) and functional (population graphs/landscape genetics) connectivity between populations and communities. We also investigate the link between spatial networks, population graphs, and host-parasite networks using multilayer networks. The main assets of this project (unique dataset, rare application of networks analyses to host-parasite interactions, and combination of spatial and ecological networks) will allow filling a gap in the understanding of global environmental change effects on biodiversity from both ecological and evolutionary perspectives. In addition, this project will provide valuable and concrete results (including new developments of an existing software) for land-use planning in the framework of current environmental policies. Besides, this project is connected to animal and human health through the “One- Health” concept, as changes in host-pathogen interactions induced by human activities can lead to emergence of infectious diseases.

Liver X receptors (LXRs) are oxysterol-activated nuclear receptors involved in the regulation of cholesterol homeostasis and in the control of inflammation. In contrast to the large number of studies investigating the impact of LXR on cholesterol homeostasis, the role of LXRs in the regulation of fatty acid (FA) metabolism in macrophages and its functional consequences have been overlooked. Nevertheless, recent studies suggest that regulation of macrophage functions such as inflammatory response and efferocytosis are tightly linked with the modulation of FA/glycerophospholipid metabolism. The general goal of this project is to assess how modulation of FA metabolism by LXRs affects macrophage functions in the context of cardio-metabolic diseases and autoimmune diseases with a specific emphasis on the secretion of pro- and anti-inflammatory lipid mediators and efferocytosis. To this aim, we will target an LXR-regulated gene that is an important modulator of polyunsaturated fatty acid (PUFA) metabolism in macrophages, controlling arachidonic acid (AA) incorporation into glycerophospholipids: the lysophosphatidylcholine acylCoA transferase 3 (LPCAT3). We will investigate the impact of LPCAT3 on key macrophage functions such as efferocytosis and inflammation and we will assess how it interferes with the previously demonstrated LXR-regulation of these pathways. In parallel, we will explore the relevance of the LXR-LPCAT3 pathway on pathophysiological processes in vivo including atherosclerosis and clearance of apoptotic cells. To answer these questions we will use a combination of in vitro and in vivo approaches using primary human and mouse macrophages and genetically engineered mouse models (Lpcat3-/- mouse and lysM-or CD11c-Cre Lpcat3flox/flox mice) with bone marrow transplantation strategy. This program, by targeting LXR/FA metabolic pathways may unravel new and original mechanisms associating LXRs, FAs and macrophage functions.

Developmental anomalies are an extremely heterogeneous group of disorders comprising over 3,000 distinct clinical entities characterized by multiple congenital anomalies often associated with intellectual disability. Most are Mendelian disorders resulting from highly penetrant genetic variants. Over the last decade, different technologies have successfully applied in translation of research findings into routine diagnostic genetic testing, including genomic microarrays for the detection of copy number variation (CNV) and whole exome sequencing for clinically and genetically heterogeneous disorders at SNV. The unbiased genotype-first approach of WES, circumventing the a priori need of an accurate clinical diagnosis to find the genetic etiology of disease, has been introduced as a first-tier clinical diagnostic test for patients with clinically and genetically heterogeneous disorders in many academic centres in the Europe and worldwide. However, despite these recent advances, identifying the underlying genetic defects remains challenging for a majority of patients. More recently, Whole-genome sequencing (WGS) has been used, presenting some additional advantages, because it can detect a broader range of genetic variation than other sequencing approaches, including not only single nucleotide variants (SNVs) and insertion or deletions (indels), but also structural variants such as copy number variants (CNVs) and translocations. Moreover, far less than 1% of the human genome shows a clear etiological association with known Mendelian diseases, while a more preponderant though variable fraction, involved in regulatory function, owns a less-known clinical relevance. The combination of additional molecular techniques such as targeted RNA quantification or total RNA sequencing (RNA-seq) may be so required to identify causal non- exonic single nucleotide variants (SNVs).

During the last five years, our GAD team, FHU TRANSLAD, has rapidly become the most recognized French reference center for the analysis and clinical interpretation of WES data in the context of rare diseases, because of our interdisciplinary approach resulting from the intermingling of complementary professional specialties. Based on this strong and well-consolidated expertise, our group now aims to move a step further and pro-actively develop an integrate analysis of WGS and RNA-seq, in translational research in order to identify new genes and new molecular mechanisms responsible for rare diseases with developmental anomalies.

This project will play a major role in the Medical Institute of Genomic Medicine and Immunotherapy, GIMI, of Bourgogne Franche-Comté, and will so contribute to develop a truly multidisciplinary pilot centre for implementing integrated WGS and RNA-seq analysis and possibly additional multi-omics (ChIP-Seq, ATAC- seq and 4C/Hi-C) in translational research in the context of the new French “France Genomics Medicine 2025”.

We evolve in Earth’s gravitational field. The brain must integrate the action of gravity (G) on the body to produce coordinated movements. Surprisingly, how the brain deals with G during the preparation and execution of movements has been overlooked. We have built a consortium (1 French, 1 USA with his own NIH grant) to decipher the basic mechanisms implemented by the brain to specifically cope with G to control motor actions. Using complementary techniques (e.g., kinematics, transcranial magnetic stimulation (TMS), peripheral neural stimulation (CMEP H-reflex), EEG, EMG) in young (in 1g and 0g conditions during parabolic flights) or elderly (1g condition) participants and vestibular-defective monkeys, we will test the main hypothesis that internal models allow the brain to predict the effects of G on movements and to tune the motor commands accordingly. Specifically, by examining kinematic and EMG features of arm movements in different directions and from different body positions in young and elderly people, we will investigate how the brain internally represents G. Using TMS, CMEP and H-reflex, we will test the hypothesis that the control of upward and downwards movements depends on G-related cues, but recruits differently the primary motor cortex and spinal cord circuits. With experiments performed in normal- and micro- gravity during parabolic flights or simulated microgravity (WP4), we will test how the brain learns and updates internal models (0g and 1g), which is thought to be critical for movement planning and control. Our hypothesis is that to build up an internal model of G, the brain strongly relies upon vestibular information. This will be tested  by investigating the potential role of G-related  otolith  signals for controlling limb movements in healthy and labyrinthectomized macaques. We will give a high priority to the project management and to the dissemination of the results throughout the GravitArm project.

After the end-Permian mass extinction (~252 Ma), marine environments are usually considered as highly depauperate, especially for benthic organisms. The recent discovery of a new paleontological locality from the earliest Spathian of the western USA basin challenges this commonly assumed scenario. This assemblage –the Paris Biota– unveils a spectacular and unexpected diversity and complexity showing a mix of primitive species from the early Paleozoic and first direct ancestors of modern forms. The Early Triassic is therefore a crucial interval in the development of modern ecosystems and the western USA basin shows a key fossil record for the understanding of their installation. This project is devoted to determine the spatio-temporal extent of the Paris Biota as well as environmental conditions that influence its formation and preservation.

This project fits into the framework of the future research federation of mathematics which includes the IMB and the LMB. The present project involves one team in each of the two institutes. The main goal is to use the complementary expertise of these two groups to develop the theme of motivic invariants both from a geometric and an arithmetic point of view.

It is a major insight of the preceding two centuries that one can use a geometrical language to study the solutions of a given set of polynomial equations with coefficients in an arbitrary field, such as the complex numbers or even in an arbitrary ring, such as the integers. The corresponding objects, called algebraic varieties, are extremely rich and mysterious due to their dual nature, geometric and arithmetic. The driving force of our project is the use of the recent and powerful theory of motivic A1-homotopy introduced by Voevodsky to produce new, and study classical, invariants of algebraic varieties of both geometric and arithmetic nature. The expected applications have a very wide range: advances in the understanding of Voevodsky’s theory, producing new knowledge in affine algebraic geometry, extending previously known computations of invariants for families of algebraic varieties, and improvement of our arithmetical knowledge of certain kinds of algebraic varieties. This wide spectrum can only be achieved by unifying the strengths and experiences of our two laboratories, IMB and LMB.

The project leader and the team of the IMB have a strong experience in the study of the algebro- geometric aspects of the project. The experimental or numerical aspects are also very beneficial. They give a deeper understanding and a finer intuition of complicated objects and abstract concepts. The members of the LMB have a thorough experience from a long-term practice of computer calculation and algorithmics that will greatly reinforce the entire project.

The objective of HS-bio-SMM project is the implementation of scanning microwave microscopy (SMM) on high-speed atomic force microscopy (HS-AFM) to characterize the morphology and the electrical properties of biological membranes under physiological environment. We expect to answer relevant biological questions about the composition and charge organization of the biochemical components of model and native membranes, without labeling and with a spatial resolution inaccessible to other techniques. We have defined specific aims: (i) implementation of SMM on tip-scan HS-AFM, (ii) application on model membranes, (iii) application on cells. The long term goal of this project is to establish the combined HS-bio‑SMM methodology for a systematic characterization of the organization and surface charge density of cell membranes. Our project aims to reveal the variation of electric properties of buccal cells after saliva interactions (coll. INRA Dijon).

Cancer cells abundantly express HSP70. As a consequence, a) they are resistant to cell death stimuli; b) only cancer cells, but not normal cells, release exosomes with HSP70 on their membrane. Our objectives are: 1) to detect those HSP70-exosomes for cancer diagnosis purposes. Since one single cancer cell can release thousands of HSP70-exosomes, we propose their detection in the blood and urines for early metastasis detection (patent PTC/EP2015/063186). 2) In order to have information about the origin of the metastasis, we will determine the bio-markers signature (particularly micro-RNAs) of the circulating exosomes. 3) We will study their role in the tumour microenvironment. 4) Toward a more personalized medicine, we will select the patients, in term of HSP70-exosomes content, that might benefit the most from our HSP70 inhibitors therapy that we develop (both peptides and chemical molecules).

The main objective of the BIONANOCAR project lies in the development of bioresorbable nanocarriers characterized by a long-lasting circulation time in order to plentifully exploit the promising potential of the ultrasmall gold nanoparticles for image-guided radiotherapy. For achieving this goal, two different strategies based on different nanocarriers will be explored. The first one rests on the grafting of ultrasmall gold nanoparticles which exhibit high potential for radiotherapy guided by simultaneous PET/MR imaging onto iron oxide nanoflowers while the second strategy will consist in the encapsulation of these gold nanoparticles in PLGA nanoparticles. The role of the bioresorbable nanocarriers is not restricted to the transport of the radiosensitizing gold nanoparticles. Indeed, nanoflowers are expected to behave as negative (T2) contrast agents for MRI and nanoheaters for magnetic hyperthermia while PLGA nanoparticles allow the co-encapsulation of gold nanoparticles with chemotherapeutic drugs. The interdisciplinary nature of the BIONANOCAR project (organic chemistry, material chemistry, colloids, in vivo imaging and radiotherapy) incites four partners (UTINAM, ICMUB, EA4267 and CGFL) with very complementary knowledge  and  skills to collaborate on the  development of these original nanotheranostics which  are expected to improve the control growth of solid tumor by radiotherapy.

To achieve the goals of this three year project, the work program has been divided into eight work packages (WPs): six complementary scientific WPs and two WPs devoted to the project coordination and the communication.

The valorization of huge amount of data is a major challenge of the current economy. These data are produced frenetically by our society and the storage is a complicated environmental and economic problem. Failing to solve this problem, it is highly desirable to transform these Big Data into an economic manna. This is possible by ranking and organizing these huge amounts of data in order to extract relevant information which in return could be used by academic research, public institutions, or private companies. GNETWORKS is an interdisciplinary project which will participate to this valorization in various domain such as human and social sciences (digging Wikipedia data), economy (digging world trade data from UN, OECD, WTO), and even health domain (digging omic data).

Big Data sets can be represented by a complex network to which a Google matrix can be associated. The Google matrix represents Markovian transitions between the different nodes. The matrix class to which Google matrices belong have practically never been studied by physicists. Using concepts from Random Matrix Theory and quantum chaos, the GNETWORKS project will analyze the fundamental features that determine the efficiency of information flow on directed networks. From Google matrix, it is also possible to extract relevant information concerning Big Data. This is performed using ranking algorithms sharing the same theoretical  basis  as the PageRank algorithm proposed  by Brin  and  Page, co-founders of  Google company. The very recent development of the reduced Google matrix method allows to identify hidden communities in Big Data. Indeed, this method allows to focus on a subnetwork of the datasets and allow establishing hidden links (long range links) between two non-directly linked nodes.

The main ambition of the project is to characterize typical and atypical development of emotional facial expression recognition in multisensory contexts. Four lines of enquiry will be engaged:

(1) Characterize how the ability to discriminate facial expressions develops from early infancy to adulthood in measuring innovative neural markers of discrimination;

(2) Understand how the non-visual, multisensory context influences the development of the ability to infer emotional state from others’ faces;

(3) Investigate the extent in which deficits in multisensory processing can contribute to deficits in facial expression recognition, more specifically in the 22q11.2 deletion syndrome (22q11.2DS);

(4) Develop and adapt an innovative electrophysiological technique to measure neural markers of cognitive mechanisms and integrative processes in infancy and developmental disorders.

In France, 15 to 38% of elderly people living in nursing homes suffered from malnutrition compared with 4 to 10% of elderly people living at home. Without presuming any cause and effect relationship between dependence and malnutrition, it is clear that despite the resources deployed for the support of dependent elderly persons, the risk of malnutrition remains high in this population.

In such a context, the project ENGAGE aims at exploring the potentiality of empowering the elderly in the meals to maintain (or restore) food intake in institution, an essential condition for preventing malnutrition and its burden on autonomy, health and quality of life.

ENGAGE will develop ‘engaging strategies’, namely interventions that allow institutionalized elderly people to stay involved in food activities, accommodating their expectations and preserved abilities. Two levels of intervention will be targeted: i) interaction between the elderly and the meal – how to provide the elderly with choice in a meal situation; ii) interaction between the elderly and the kitchen – how to keep the elderly involved in food preparation.

Development of engaging strategies will use participatory research and living lab’s methodology centered on the final user (co-creation). Key stakeholders (eg elderly people, institution staff, catering staff) will be involved in the development of interventions to take into account the expectations and the capacities of the elderly as well as the socio-economic constraints of the institutions. Effectiveness of engaging strategies will be assessed and put in balance with applicability in the field. Evaluation of strategies will consist of experimental trials and consider improvement in appetite and food intake as benefits for the elderly, as well as strategies cost and feasibility in the field. Finally, communication of ENGAGE results will be supported by dissemination, take-up and training actions.

The project Food2C studies the way that foods are provided to urban consumers today. It is a multidisciplinary project, which combines social sciences with food sciences. Food2C aims to analyze food supply chain organizations and food conservation technologies of vegetable products in three agglomerations: Dijon Metropole in France, Nha Trang and Hanoi agglomerations in Vietnam. Comparative studies between two countries allow to identify underlying factors that condition successful application of local food system. Mobilizing the foodshed approach, and considering the use of fermentation as a low-technology applicable at a large scale by familial and semi-industrial structures, the project is looking to produce a proof of concept of local food system, which could be developed in France by local food operators. It contributes to the scientifc debate over the efectiveness of local food system as an answer to global food security challenges that we are facing in next decades.

The project seeks to instigate and strengthen the interdisciplinary continuum within UBFC by  bringing together researchers to further our knowledge of the territory of the Sequani in eastern France (partially Bourgogne-Franche-Comté), its boundaries, organization, its population and their habits from the conquest by Julius Caesar to the reforms of Diocletian (1st c. BC – late 3rd c. AD). It involves collecting, indexing, preserving, analysing and restoring data using digital tools (databases, 3D technologies) in order to enhance archives, archaeological sites, numismatic and epigraphic material, so that researchers and the general public can trace the history of a region, the articulation of economic, cultural and human exchanges locally, regionally and provincially and the potential constitution of a Sequani identity within the Roman Empire.

Historians, archaeologists, epigraphists, museum or collection directors are thus at the crux of the questions facing the new region of Bourgogne-Franche-Comté in that they can show how exchanges with neighbouring polities were organized and how economic and cultural networks were formed in Roman times, all of which are contemporary challenges too. The project is therefore very much part of the latest trend of future-oriented research based on a questioning of the past. How can we preserve, restore and model buildings and epigraphic and numismatic material? How can we account for the appearance of a territory that has been re-shaped by time so as to make available to the scientific community and the general public a heritage that constitutes a common history? What interactive methods can be imagined to share this knowledge widely while ensuring its scientific value? These are the questions researchers brought together from various disciplines are to endeavour to answer by reappraising and comparing available sources in a way made possible by the inclusion of multiple epistemological approaches to the territory of the Sequani.

In the context of changing working conditions for caregivers, the Project RELA@TIONS (Relations, Communication, and Health), aims to measure cross-perceptions that caregivers and patients have of the quality of the care-grooming relationships. We analyze on the one hand the impact of the perceived (represented) working conditions by caregivers (stress, anxiety-depression, quality of working life) ; and on the other hand the consequences on the health education of the patient, with a special focus on the behavioral intentions regarding the implementation of good practices, in particular nutrition and physical activities. The REL@TIONS project proceed with in-depth interviews then questionnaire with the two populations – caregivers (N=90) and patients (N=90) – in care services at the university hospital of Dijon: cardiology, visceral surgery, internal medicine and geriatrics. We chose these services for their differentiated level of technical complexity.

This project aims firstly to measure the quality caregiver-care relationships, directly related to caregivers’ working conditions and to patient health education; secondly, it focuses on the training of caregivers, particularly in establishing a Master’s degree in “advanced practices” for health professionals, specifically nurses.
