Resume

PhD from the University of Aix-Marseille II (Centre d'Océanologie de Marseille) in the field of Marine Biology (thesis on the biochemistry of respiration in a marine bacterium). Teaching activity at a Higher Education Institution since 1991. The scientific work performed to this date may be resumed as PROTEIN BIOCHEMISTRY. This covered essentially the study of proteins involved in the respiratory systems of microorganisms, in particular the denitrification pathway, a key process of the Biological Nitrogen Cycle: this phenomenon is important regarding its applications (fight against pollution, biotechnology, agriculture) but also from a fundamental point of view (original catalytic centres, ecological importance of the biological nitrogen cycle). Enzymes and electron carriers are purified from bacterial cultures, and then characterized (enzymology, spectroscopy,...). Another aspect of the work deals with the proteomic studies of animal venoms. Fast evolving proteic components of venoms represent an excellent biological material for the study of structure/function relationships. Also responsible for processing data from oceanographic campaigns at the Research Institute of Dhahran (King Fahd University, Saudi Arabia) in 1989-90.
