McMahon, Robert J. - University of Wisconsin-Madison

个人简介

Robert J. McMahon was born in Mendota, Illinois in 1958. He received a B.S. degree in Chemistry from the University of Illinois at Urbana-Champaign in 1980. He performed undergraduate research with Professor Stanley G. Smith into the mechanism and stereoselectivity of lithium aluminum hydride reduction of ketones. McMahon received a Ph.D. degree in Organic Chemistry from the University of California, Los Angeles in 1985, working with Professor Orville L. Chapman on the mechanisms of carbene rearrangements. From 1985-1988, McMahon investigated excited-state electron transfer as a postdoctoral research associate with Professor Mark S. Wrighton at the Massachusetts Institute of Technology. McMahon accepted a position on the faculty in the Department of Chemistry at the University of Wisconsin-Madison in 1988 and was promoted to full professor in 1997. He was named an Associate Editor of the Journal of Organic Chemistry in 2000 and a Fellow of the American Association for the Advancement of Science in 2003.
