I am interested in bacterial metabolisms, in particular how bacteria can adapt to several substrates to sustain growth in changing environments. During my PhD, I focused on the characterization of the molecular actors (metalloenzyme) of bacterial metabolism using biochemical, biophysical and structural approaches. During my first postdoc (Sargent Lab, UK), I have been interested into the hydrogen (H2) metabolism of Escherichia coli. My objective was to rewire E. coli for carbon dioxide (CO2) fixation using H2 as energy source, something which is not expected by the bacteria in Nature. Using synthetic biology combined with chemical engineering, I designed an efficient laboratory-scale bioprocess for the conversion of CO2 into valuable chemicals. Keeping with this research continuum, I joined the BIP laboratory (Giudici Lab) for a second postdoc which aimed at deciphering the metabolic interactions network between two bacteria involved in the process of microbial bio-H2 production using cell biology and quantitative proteomic approaches. Following my recruitment in 2022, I am now trying to unveil the molecular basis of bacterial cooperation by developing new ecological models. In particular, I am currently interested in the role of quorum sensing in triggering bacterial interactions and its link with the metabolic activity of microbial communities.
