Guy Bertrand is a chemistry professor at the University of California, San Diego. Bertrand obtained his B.Sc. from the University of Montpellier in 1975 and his PhD from the Paul Sabatier University, Toulouse, in 1979. He was a postdoctoral researcher at Sanofi Research, France, in 1981. The research interests of Bertrand and his co-workers lie mainly in the chemistry of main group elements from group 13 to 16, at the border between organic, organometallic and inorganic chemistry; especially their use in stabilizing carbenes, nitrenes, radicals and biradicals, 1,3-dipoles, anti-aromatic heterocycles, and more. He has directed the synthesis of some original persistent carbenes, including bis(diisopropylamino)cyclopropenylidene, the first example of a carbene with all-carbon environment that is stable at room-temperature. Guy Bertrand is an honorific member or fellow of several scientific societies, such as the AAAS (2006), the French Academy of Sciences (2004), the European Academy of Sciences (2003), Academia Europaea (2002), and the recipient of various prizes and awards.
