Born in 1963, David studied Chemistry at the University of Strathclyde, Scotland, obtaining his BSc in 1983 and PhD in 1986. His doctoral research on the chemical modification of enzymes with a view to generating new catalysts for organic chemists was carried out with Hamish Wood and Colin Suckling. Following a NATO-Royal Society post-doctoral fellowship working with Henri-Philippe Husson at the Institut de Chimie des Substances Naturelles, Gif-sur-Yvette (1987-89) he was appointed CNRS Researcher in the new Husson group at the University of Paris 5, working mainly on the stereoselective preparation of cyclopropane-containing compounds through the exploitation of aminonitrile chemistry. In 1998, he became Professor at the University of Clermont-Ferrand 2, where he set up a new research group working on photochemical routes to cyclobutane β-aminoacids and the development of methodologies for the total synthesis of macrocyclic peptides containing β-aminoacids. In 2006, he transferred to his present position as Professor of Organic Chemistry at Orsay. Research interests include all aspects of synthetic methodology, including photochemistry, and the preparation of molecules and molecular scaffolds of biological and therapeutic interest. He is currently Director of the ICMMO research institute.
