Human Nutrition: in various national and international projects, conducted by the Human Nutrition unit or other research labs, the expertise of PFEM is to study metabolic deviations associated with development of chronic metabolic diseases, using proteomics, metabolomics and fluxomics. The specific objectives are: (i) to identify early and/or predictive biomarkers of these deviations for a better metabolic phenotyping and stratification of at risk populations; (ii) to better understand the biological mechanisms involved in these pathophysiological processes. 

Animal Physiology and Foods Quality: the PFEM expertise is used in several national and international collaborative programs to achieve different objectives such as the identification of new biomarkers related to animal mycotoxins exposure, traceability of micronutrients in livestock, nutritional quality of milk and meat products, molecular determinants involved in stress adaptation, antibiotic resistance or ability to form biofilms of pathogen microorganisms (L. monocytogenes, E. coli, Salmonella, S. aureus, etc), identification of proteins from different varieties of wheat in relation with the gluten content. 

Environment and biological systems: in various national and international projects, conducted directly by the platform or by different CNRS/University laboratories, the PFEM's task is to evaluate the influence of external environmental stimuli on biological systems. This expertise appears in different collaborative programs to study the effects of pesticides, emerging pollutants, atmospheric environments on microorganism ecosystems in soil, waters and clouds.
