Prof. Sanyi Tang is interested in the nonlinear dynamic systems arising in biology, agriculture and life sciences. Of particular research interest is at the interface of Mathematical biology. In recent years, he has published more than 80 papers in top international journals of Applied Math. and Biol. Math.. He was/is the PI of three grants funded by NSFC and one grand funded by HIH-HSFC. He has many years of experience in developing hybrid differential equation models and analytical methods for integrated pest management research, emerging infectious diseases and HIV/AIDS research, and he was involved in the interdisciplinary program for cellular regulation about four years in the University of Warwick, UK. He also joined the modeling sub-project of the National Mega-project of Science and mainly focused on analyzing the surveillance data and developing computation methods. He is directing the Division of Applied Mathematics to perform bio-mathematical modeling in infectious diseases and population dynamics.
