Prof. F. Treussart (FT) leads the “Biophotonics and Physiopathologies of Synapses” team at Laboratoire “Lumière, Matière et Interfaces” (CNRS, ENS Paris-Saclay, Univ. Paris-Saclay, CentraleSupélec, France). FT studied Physics and Chemistry at ENS and specialized in quantum optics and lasers. Following a PhD at the Kastler Brossel Laboratory (Paris), he was recruited as an assistant professor at ENS Paris-Saclay in 1998 where he developed an expertise in the spectroscopy of single emitters and nanocrystals. In 2006 FT was promoted Professor and initiated the applications of fluorescent nanodiamonds (FND) to bio-imaging in collaboration with Huan-Cheng Chang (Taiwan). Recently, in collaboration with Michel Simonneau (Prof. Emeritus, Dept of Biology, ENS Paris-Saclay), FT invented a technique based on tracking single FND in neuronal branches to reveal slight abnormalities in intraneuronal transport linked to neuropsychiatric disorders. He is now extending this approach to human brain organoids and to small animal in vivo (zebrafish larvae).
