Biography
Yonghyun Shim received his B.S. degree from Seoul National University, Seoul, the Republic of Korea in 2007 and M.S. degree from the University of Michigan, Ann Arbor in 2009, both in Electrical Engineering. He was the first student member of the Resonant MEMS group and received his Ph.D. degree in Electrical Engineering from UM. He joined Broadcom in August 2013. His research interests include Wireless Transceiver, RF Filter, and CMOS-MEMS integration.
