Additional Information:

K. N. Houk was born in Nashville, Tennessee in 1943. He received his A.B. (1964), M.S. (1966), and Ph.D. (1968) degrees at Harvard, working with R. A. Olofson as an undergraduate and R. B. Woodward as a graduate student in the area of experimental tests of orbital symmetry selection rules. In 1968, he joined the faculty at Louisiana State University, becoming Professor in 1976. He has also been a Visiting Professor at Princeton. In 1980, he moved to the University of Pittsburgh, and in 1986, he moved to U.C.L.A., becoming a Distinguished Professor in 1987.

He has served on the Advisory Boards of the Chemistry Division of the National Science Foundation, the Petroleum Research Fund, a variety of journals, including Accounts of Chemical Research, the Journal of the American Chemical Society, the Journal of Organic Chemistry, Chemical and Engineering News, the Journal of Computational Chemistry, Chemistry-A European Journal, and the Journal of Chemical Theory and Computation. He was a member of the NIH Medicinal Chemistry Study Section and the NRC Board of Chemical Sciences and Technology. From 1988-1990, he was Director of the Chemistry Division of the National Science Foundation. He was Chairman of the UCLA Department of Chemistry and Biochemistry from 1991-1994 and was Chair of the AAAS Chemistry Section in 2005. He is a Fellow of the American Academy of Arts and Sciences, the American Association for the Advancement of Science, and of the World Association of Theoretical and Computational Chemists (new name of WATOC). He was co-chair, with Professor Cynthia Friend of Harvard, of a NSF-NIH-DOE-sponsored Workshop on Building Strong Academic Chemistry Departments Through Gender Equity in 2006. He currently is the Director of the UCLA Chemistry-Biology Interface Training Program and Senior Editor of Accounts of Chemical Research. He is a member of the NIH SBC-A Study Section and is Chair for 2007-2008. On July 1, 2009, he becomes the Saul Winstein Chair of Organic Chemistry at UCLA

He has published more than 750 articles in refereed journals, is among the 100 most-cited chemists, and is an avid runner, biker, and swimmer.
