Brief Biography
Dr. Hargsoon Yoon earned his Ph.D. degree in Engineering Science from Pennsylvania State University in 2003. He received his B.S. and M.S. degrees in Physics from Yonsei University, South Korea. Dr. Yoon also worked at Hynix Semiconductor Co. as a senior research engineer and a task force leader for system integrated circuit device development for seven years. After working as a post-doc at Pennsylvania State University and a research associate professor at University of Arkansas, he joined the Department of Engineering at the Norfolk State University in 2010.

He is the director of Nanotechnology Cleanroom Facility and the founder of Neural Engineering and Nano Electronics laboratory in NSU. He served as the Guest Editor of Journal: Biosensors, Special Issues on Neural Sensing and Interfacing Technology. He is currently serving as an Associate Editor for Special Section Nanodevices of Journal: Frontiers in Nanotechnology and a program committee of SPIE international conference for Nano-, Bio-, Info-Tech Sensors and Systems. Dr. Yoon is also a senior member of the IEEE Engineering in Medicine and Biology Society and a member of Society for Neuroscience.
