Sung-Min Sohn is an assistant professor in Department of Radiology at University of Minnesota Medical School. He received the B.S. and M.S. degrees from Korea University, Seoul, South Korea, in 2002 and 2004, and the Ph.D. degree from Department of Electrical and Computer Engineering at the University of Minnesota, Minneapolis, MN, USA, in 2013. From 2004 to 2007, he was a Circuit Design Engineer with the Analog and Mixed signal Circuit Group, LG Electronics, Seoul Korea. His current research interests include RF/analog/digital circuits and systems for MRI electronics and novel RF coil and interface hardware design. He was awarded a K99/R00 Pathway to Independence Award from NIH (NIBIB) as one of five awardees in the field of biomedical imaging and bioengineering in 2016. This grant support him to became an independent faculty member with ~ 1M dollars for five years (Feb. 2016 – Jan. 2021).
