	Research Interests and achievement
Updated on September 3, 2006 Tsun-Hsu Chang received his B.S. degree from National Central University in 1991 and his Ph.D. degree from National Tsing Hua University in 1999. Upon graduation, he worked as a postdoctor on the development of high power millimeter wave sources (gyrotrons) for two years. From 2001 to 2003, he served as a technical manager at Silicon Integrated System Corporation and was responsible for high-speed signal and power integrity analysis in both simulation and measurement. He is currently an Associate Professor with the Department of Physics, National Tsing Hua University, Taiwan. His current research focuses on the nonlinear dynamics of the electron cyclotron maser, high power sub-Terahertz physics, and the characterization of the microwave/nano- particles interaction.
