Chef d'équipe / Group leader: BIP 01

– Director of the Mediterranean Institute of Microbiology (IMM, 4 laboratories, 9 technical platforms and about 350 members),
– Head of the biomass platform hydrogen CNRS Aix/Marseille University.
– Member of the National research evaluation « section 20 » biochemistry, bacterial metabolism,
– Member of the board HCERES committees: evaluation of laboratories: Chair, vice chair, member
– Member of « Cellule Energie du CNRS » in charge of biomass and bioenergy topics
– Member of the editorial board of FEMS microbiology review.

My research is focussed on the main metabolic chains of micro-organisms involving metalloenzymes, complexes and supercomplexes. After having studied their characterization, I am interested now in the understanding of their dynamics and interactions under different conditions. I have initiated an innovative axis, which consists in the microbial study of bacterial consortia involved in bioH2 production.
I have expertise for implementation between research, training, innovation and valorization.
