Pr Thierry LEQUEUX
Full professor
Section du CNU n°32
Thierry Lequeux was graduted from the University of Orsay (Parsi XI). He obtained his PhD in 1994, under the supervison of Dr Jean-Pierre Bégué and Dr Danièle Bonnet-Delpon on the study of the role of the CF3 group in cycloaddition reactions. After a post-doctoral position in the group of Pr Jonathan Percy at the University of Birmingham (UK) on synthesis of difluoromethylphosphonates as analogues of phosphates (3′-modified nucleotides), he was appointed Lecturer in fluorine chemistry, and then full Professor at the University of Caen (France). His current research interests are focus on the preparation of fluorinated biomolecules, and biopolymers to prepare acyclonucleosides, enzyme inhibitors and fluorinated polymers for tissue engineering. He is member of the GIS Fluor, the French Fluorine Network .
