Fabrice Rappaport is Research director at the CNRS. He graduated in Biophysics from the Pierre et Marie Curie University and from the Ecole Normale SupÃ©rieure in Paris. He joined JÃ©rome LavergneÂ¿s group in Pierre JoliotÂ¿s lab and obtained his PhD, in 1994, for his work on the release of proton associated with the turnover of the water splitting enzyme in Photosystem II. He then moved to Imperial College, London, to work, as a postdoctoral fellow, with David Klug and James Barber. In 1997, he was appointed by the CNRS and moved back to Paris and the Institut de Biologie Physcio-Chimique held, at this time, by Pierre Joliot and now by Francis-AndrÃ© Wollman. There, his research aims at understanding the function of the main complexes of the photosynthetic chain with an emphasis on the thermodynamics and kinetics aspects. He recently expanded his studies to mitochondria and the respiratory chain. He stood as board member of the French Society for Photosynthesis.
