Prof. YAO Xiaoqiang (姚曉強) obtained his degree of Bachelor of Science in Biology in 1981 from Department of Biology, Hangzhou University, Zhejiang, China. In 1984, he obtained his Master of Philosophy degree from Chinese Academy of Sciences.  He then obtained his Ph.D. degree in 1991 from Department of Biological Sciences, The State University of New York at Buffalo, USA.  After that, he had postdoctoral training in Department of Internal Medicine, Yale University School of Medicine, USA.  In 1996, he became an Assistant Professor in Department of Physiology, The Chinese University of Hong Kong, and later was promoted to Associate Professor in 1999 and Professor in 2002.  He is now the Chief of Neural, Vascular, and Metabolic Biology Thematic Research Program in the School of Biomedical Sciences, The Chinese University of Hong Kong.  His research interest is mostly on ion channels in cardiovascular system and cancer cells.  These include TRP channels and K+ channels. He has published more than 230 original articles with total citation of >10600 with h-factor of 55, including those in Proc Natl Acad Sci USA, Nature Communications, Circulation Research, Journal of Clinical Investigation and Trends in Pharmacological Sciences.
