Actual position and research subject

I am a researcher at the National Institute of Agronomic Research (INRA) in bioprocesses engineering from 2008.My work focused on the characterization of solids (physical and biochemical) to predict their anaerobic biodegradability and understand their biodegradation. Since my recruitment, I was involved in national research projects (3 contracts ANR, and one of the INRA institute), one European and one funded by the Carnot Institute (3 projects and 2 as a coordinator). I supervised or co-supervised PhD students, three postdocs, one engineer, 11 master degree students and 2 technician students. In parallel to my research activities, I was teaching in the University Technological Institute (between 30 and 40 hours per year).In september 2014, I move to the team Microbial ecosystem and purification and recovery processes in the Laboratory of Biological Systems and Processes Engineering (LISBP). My research focuses on link between transfer phenomena and microbial reactions. Particularly I am working on the microbial processes that occur during the solid state-fermentation of the residues (i.e. wastes, lignocelllulosic biomass…) in bioprocesses with the view to valorization the organic carbon and to understand and optimize the interaction between microbes and substrates during these microbial transformations. Another large part of my activities concerned the CO2 (and CO) transformation towards energy (biological methanation) and platform molecules (gaseous fermentation) Now, I am involved in 1 national ANR project and coordinator of precompetitive TWB project. Since January 2021, I am animating the team SYMBIOSE at TBI
