Dr. Philippe Lesot, born in October 1967, has been Research Director since 2007 at Institut de Chimie Moléculaire et des Materiaux d’Orsay (ICMMO) (France) located at Orsay (University of Paris-Sud/Paris-Saclay).  He is affiliated to the french National Center for Scientific Research (CNRS since 1997.  

He received his Ph.D degree (cum laudae) at University of Paris-Sud (Orsay) in 1995 (supervisor: Prof. J. Courtieu), and then pursued his NMR research activities at University of Southampton (UK) with Prof. J.W. Emsley, awarded by both a grant from the Royal Society of London and the French Foreign Ministry (Lavoisier).  

After holding a temporary assistant professor position at Orsay for one year, he joined the CNRS in 1997.  He was a recipient of the 2001 Bronze Medal from CNRS for young scientists for his pioneering work on the Natural abundance 2D-NMR spectroscopy in chiral liquid crystals.

He has published over 110 publications in international, peer-review journals, 10 bbok chapters inclused two encyclopedian and given approx. 55 invited talks on the analytical and methodological developments in anisotropic NMR in collaboration with numerous (bio)chemists.  His current research interests focus on the natural isotope fractionation of bioproducts by anisotropic NAD NMR and the fight against counterfeiting.
