About me:

Snow H. Tseng   received the B.S. degree in physics from National Taiwan University, Taipei, Taiwan, in 1994, M.S. degree in physics from University of Chicago, Chicago, IL, in 1997, and Ph.D. degree in electrical engineering at Northwestern University, Evanston, IL in 2005.  In 2004, he was awarded the Outstanding Poster Presentation Award of the Gordon Research Conference of Lasers in Medicine and Biology; next year, he was awarded the Best Student Paper Award of the American Society of Lasers in Medicine and Surgery.  He became an assistant professor at the Graduate Institute of Electro-Optical Engineering of National Taiwan University in February 2006.  His research interests include optical interactions with biological tissues and electromagnetic wave propagation in random media.
