George Trainor received M.S. and Ph.D. degrees in Chemistry from Harvard University in 1979. Following postdoctoral studies at Columbia University, he joined the Central Research and Development Department of the DuPont Company in 1981. He initiated a program that led to the discovery and commercialization of fluorescence-tagged chain terminators for use in automated DNA sequencing, for which he received the 2011 Heroes of Chemistry Award from the ACS. From 1991 to 2010, he led teams at DuPont Pharmaceuticals and Bristol Myers Squibb, advancing over 30 drug candidates into development. He currently consults in partnership with his spouse on medicinal chemistry and drug discovery.
