James Schmidt est un spécialiste de l’apprentissage, de l’attention, du contrôle cognitif et des réseaux de neurones. Il mène des recherches expérimentales sur le contingency learning, c’est à dire la façon dont l’être humain mémorise, souvent inconsciemment, les éléments réguliers de son environnement et les utilise pour mieux interagir. James Schmidt s’intéresse également à l’attention, au contrôle cognitif et aux réseaux de neurones, avec un regard critique sur les théories classiques du contrôle cognitif. Cela inclut des travaux sur le contrôle et les conflits attentionnels ainsi que sur le changement de tâche. Ce chercheur possède une expertise considérable dans la modélisation des réseaux de neurones. Il a notamment programmé un modèle de mémoire épisodique qu’il a appliqué à de nombreux domaines de recherche. Il a également publié des travaux sur l’apprentissage temporel, le raisonnement formel, le binding et l’effet Stroop.
Mots clé : psychologie cognitive, réseaux de neurones, contingency learning, binding, attention, contrôle cognitif, timing, changement de tâche, modélisation computationnelle, mémoire épisodique.
Simon KIMBER is a materials chemist, with significant expertise in electronic and magnetic properties. He has worked in central facilities for synchrotron and neutron scattering, and made significant R&D advances in scattering techniques. He has applied these to both solid state and solution phase systems, and has recently developed an interest in the interfaces between solvated species and solvent.
X-ray and neutron scattering, in-situ measurements, materials chemistry, nanoparticle interfaces, solvent restructuring.

Pieter VISSHER wil work as a joint professor. He is currently full Professor and researcher among the leaders in the field of geomicrobiology and he is -among many other responsibilities- also co-founder of NASA Astrobiology Institute, project leader in major National Science Foundation programs, founder and chief administrator of UConn’s Center for Integrative Geosciences and collaborates with the industry (Petrobras, Unisense).
With (post)graduate degrees and extensive training in Atmospheric Chemistry, Geochemistry, Marine Sciences, Microbiology, Biogeochemistry and in Environmental Law, his specialty is in Geomicrobiology, with a focus on biosignatures in modern and recent sedimentary systems and with applications in Astrobiology. Specifically, he focuses on the role of microbial metabolism and microbial expolymers in precipitation and dissolution of minerals (e.g., carbonates, silicates). He also investigates the production and consumption of biogenic gases (e.g., volatile sulfur, methane). More recently, he has studied fabrics of microbial deposits and biotic and abiotic alterations of these during early diagenesis
Keywords : Geomicrobiology, ecophysiology of sulfur bacteria, exopolymeric substances, microbe-mineral interactions, microbial mats, quorum sensing, biogenic gases, Astrobiology.

Owing to their implication into various natural processes, porphyrins have attracted considerable attention, principally due to their high versatility and their outstanding physico-chemical properties. This project is focused on C-N+ fusion reactions with porphyrin precursors. It aims to exploit the electrochemical and chemical tools to generate unprecedented fused and charged porphyrin derivatives, mainly based on the creation of new C-N+ bond(s) with specifically designed imine peripheral substituents. These unique π-extended compounds and materials are expected to exhibit totally new physico-chemical properties, such as high absorption in the NIR, good fluorescence (for Mg, Zn and H2 porphyrins), two photon absorption, reduced LOMO-HUMO gap, increased polarity, interaction with DNA… These features will open the door to novel applications in various areas.

Nonlinear optics is one of the most important and active research areas nowadays in optics and photonics sciences, also expected to become more and more pronounced in the creation of all-optical circuitry for computing, information processing, and networking, in particular to overcome the speed limitations of electronic-based systems.Bertrand KIBLER aims to exploit, in an original way, one of the most ubiquitous types of instabilites in nature, the Benjamin-Feir instability (BFI) or modulation instability, in order to exalt the potential of high-speed electro-optics for harnessing light waves. BReathing lIGHT (BRIGHT) will explore a new class of nonlinear waves called « breathers » and relatid to BFI phenomenon. Such breathers exhibit richer dynamics that makes them unique objects in nonlinear science, with a large range of applicability that could be developped. The remarkable potential of nonlinear fiber-based platforms based on ultrafast optics and advanced pulse metrology is expected to become the ultimate ted-bed of breathers both for fundamental and applied aspects. Benefiting form their specific dynamical features, the disruptive innovation is to open the way to breather-based functionalities in ultrafast optics and develop novel optical signal processing architectures.

Charlotte SINDING will investigate the brain mechanisms of Odor-Induced Taste Enhancement (OITE) in obese and normal weight population. This project involves several domains of research, such as perception and therefore sensory evaluation (psychophysics), neurosciences (non-invasive human imagery, fMRI and EEG) as well as cognitive psychology and cognitive neurosciences.

The role of Th17 cells in cancer remains unclear. On the one hand, depending on the circumstances they seem to support tumor neuroaniogenesis, tumorigenesis and have a strong immunosuppressive potential. On the other hand, several studies in human and mice showed an anitumor role of Th17. These differences seem to depend on the cytookine environment in which Th17 are differentiated. The mechanism that controls the switch between regulatory and inflammatory Th17 cells remains elusive. Such question could be of major importance in many cancers infiltrated by regulatory Th17 cells. Deciphering the mechanisms behind the regulatory and inflammatory Th17 cells switch may help finding drugs that could favour in vivo this switch. This project aims to demonstrate that NLRP3 participates in Th17 differentiation and drives the regulatory and inflammatory Th17 cells balance.

Because cancer cells re-wire their metabolism, they need for their survival a high content of stress-inducible chaperones like heat shock proteins (HSPs). This cancer cells’ addiction to HSPs is the basis for the use of HSP inhibitors in cancer therapy. Several recent clinical studies have shown that one of them (still quite unknown) called «HSP110» is particularly relevant in colorectal cancer.
This ISITE project aims at deciphering the role of this HSP in colorectal cancer and to perform studies from structure to drug design in order to propose specific inhibitors that could be used in patients. Toward a more personalized medicine, they propose to demonstrate that HSP110 levels in blood samples correlated with HSP110 expression in tumor biopsies. Therefore, measuring circulating HSP110 levels will help to select the population that may benefit the most from the proposed HSP110-targeted therapy.
