r. Sun obtained his PhD degree from Shanghai Jiao Tong University, China. In the last semester during his PhD study, he visited Theoretical Epidemiology group, Instituto Gulbenkian de Ciencia in Portugal. Before joining KMUST, he worked at Department of Biology, McGill University, later he moved to University of Manitoba, and most recently, he worked in The University of Hong Kong as a Researcher. His research focuses on infectious disease transmission in plants and human beings and its prediction, prevention, and control via vaccination. He pays particular attention to HIV infection in core groups.

Research Interest

His research interests include: Mathematical and theoretical biology, Epidemiology, Immunology, Differential equations and Applications.
