I am currently pursuing my Ph.D degree at Electrical Engineering department, University of Washington. I am now a research assistant working with Prof.  Leung Tsang in Laboratory of Applications and Computations in Electromagnetics and Optics (LACEO). My current research focuses on the rough surface effect on the signal integrity for transmission lines on the printed circuit board. My research interests includes theoretical and numerical studies of electromagnetic wave propagation in complex environment, especially for signal integrity problems.
