I am a Ph.D. student in ECE at Michigan State University. I work with Professor Robert J. Mcgough in the Biomedical Ultrasound and Electromagnetics Laboratory. I received my M.Sc. in EEE from the University of Sheffield, UK in 2003, and my B.Sc. from the Department of Electronic Science and Engineering, Nanjing University, P. R. China in 2002. I was a research assistant in the State Key Lab of Modern Acoustics, Nanjing University from 2001 to 2002.

Research

My research focuses on the numerical modeling of ultrasound transducers and phased arrays for hyperthermia thermotherapy. My projects involve

Development of fast pressure simulation algorithms in both integral methods and angular spectrum approach

Design of transducers and arrays for therapeutic and diagnostic applications

Temperature simulation and optimization of ultrasound and ultrasound/radio-frequency hybrid applicators for breast cancer therapy

My other research interests include ultrasound cavitation, medical imaging, and medical image analysis.
