Richard Hsung

Richard Hsung went to Calvin College in Grand Rapids, MI, obtaining his B.S. degree in chemistry and mathematics, and worked in Professors Ron Blankespoor and Ken Piers' Laboratories. He attended The University of Chicago and received his M.S. and Ph.D. degrees in organic chemistry in 1990 and 1994, respectively, under supervisions of Professors Jeff Winkler and Bill Wulff. After pursuing postdoctoral research at Chicago with Professor Larry Sita in 1995, he completed his training as an NIH postdoctoral fellow in Professor Gilbert Stork's Laboratory at Columbia University. In 1997, he moved to University of Minnesota as an Assistant Professor, was promoted to Associate Professor in 2002, and in 2006, moved to The University of Wisconsin-at Madison as Full Professor.
