Assistant Professor, Teaching and Research Division

Expert in natural product chemistry, chemical analysis of Chinese herbal medicines and application of high-speed counter-current chromatography.


Dr. Simon Quan-Bin Han obtained his PhD in natural product chemistry at Kunming Institute of Botany, Chinese Academy Sciences in 2003 and was granted “The President Award” by the Academy. 2004-2009, he was a Scientist at Hong Kong Jockey Club Institute of Chinese Medicine.  2009-6.2011, he worked for the Chinese University of Hong Kong as a Research Assistant Professor. Now he is an Assistant Professor at School of Chinese Medicine, Hong Kong Baptist University. 

His research interests are focused on natural product chemistry, quality control methodology, HSCCC’s application in drug discovery. With years of research experiences, Dr. Han has published over one hundred research papers in scientific journals such as Natural Product Reports, Current Medicinal Chemistry, Organic Letter, Journal of Chromatography A, Journal of Natural Products, etc, being the first author for nearly forty of them. His research got financial support from several government funding agencies, like National Natural Sciences Foundation in China, HKSAR Innovation and Technology Fund (ITF), and Health and Health Services Research Fund, etc.
