Ohyun Kwon received her B.S. (1991) and M.S. (1993) from Seoul National University in South Korea. In 1993, she came to the U.S. to pursue her Ph.D. (1998) from Columbia University under the guidance of S. J. Danishefsky. Her thesis work involved the synthesis of biologically significant glycolipid, asialo GM1 and Globo-H human breast tumor antigen molecule, as well as complex phomoidride terpenoids, CP-225,917 and CP-263,114. She then went to Harvard University as a Howard Hughes Postdoctoral Fellow to study chemical genetics in S. L. Schreiber's lab. There, she completed a diversity-oriented combinatorial synthesis (DOS) of a library of muticyclic compounds, as well as a library of macrocycles. Kwon joined the faculty as an assistant professor at UCLA in 2001. She has been a member of the Molecular Biology Institute (MBI) and UCLA Jonsson Comprehensive Cancer Center (JCCC) since 2005. Her research at UCLA evolves around the development of new nucleophilic phosphine catalysis reactions. The new reaction methodologies are used in the total synthesis of natural products and in the production of libraies of small organic molecules for chemical genetic applications.
Our research interest lies in the area of development of new methodologies for organic transformations, target oriented synthesis of biologically important natural compounds, and diversity oriented synthesis of natural product-like molecules. Molecules thus built will be employed in the investigation of biologically significant processes. Each project described below encompasses more than one area of these research interests.
