Bioenergetics deals with the energy conversion especially at the membrane level of mitochondria, chloroplast and all procaryotes. My research interests are about the last component of the respiratory chain both aerobic and anaerobic. I try to understand how those membrane complexes work: specificity of electron donors (quinone interaction), how electron shuttles throw cofactors (organic or metallo-organic), and the interaction with substrate/product/inhibitors by using various approaches: enzymology on membrane vesicles or purified enzymes, Clark electrode, redox titration followed by UV-vis spectroscopy as well as EPR spectroscopy. Currently I am working on the nitrate reductase from E. coli and the terminal oxidases from D. fructosovorans.
