An got his B.S. and M.S. degrees in pharmaceutical science at Perking University, where he worked with Professor Xin-Shan Ye on the synthesis of sialylated glycopeptides as anti-tumor vaccines. He joined the Chen lab in the winter of 2014 and now he is a Ph.D. candidate in chemistry. His research interests are the enzymatic synthesis of sialidase inhibitors, and the enzymatic synthesis of sialosides containing N-acetylated sialic acids as stable mimics of the natural occurring O-acetylated sialic acids.
