Bruce H. Lipshutz

Bruce H. Lipshutz (born 1951) is an American chemist. He is a professor at the University of California, Santa Barbara.^[1]

Biography

Lipshutz received his undergraduate degree in chemistry from Binghamton University in 1973. His graduate work was supervised by Harry H. Wasserman at Yale. After a PhD degree in 1977, he spent two years at Harvard as a post-doctoral researcher in the group of Nobel Laureate E. J. Corey. Soon after, he accepted a position of Assistant Professor at UCSB rising to the ranks of Professor in 1987. He has received the Alfred P. Sloan Foundation Fellowship and the Camille & Henry Dreyfus Teacher-Scholar Award. In 2011 he was awarded Presidential Green Chemistry Award.^[2] He is Co-founder of Zymes LLC.^[3]
