Chi-Hin CHO

Research Professor


Professor C.H. Cho received his PhD in Pharmacology from the University of Hong Kong (HKU) in 1978. He went through his postdoctoral training in Canada and started his first faculty position in the Yang Ming Medical College and Veterans General Hospital Taipei in 1981. He joined HKU in the Department of Pharmacology from 1984 and became Chair Professor of Pharmacology in 2000. Later, Prof. Cho joined the Chinese University of Hong Kong (CUHK) in 2007 as chairman and Professor of Pharmacology. Currently, he is the Research Professor and Associate Director of the School of Biomedical Sciences, Faculty of Medicine in CUHK. He becomes Emeritus Professor in 2016. Professionally he was President (2006-2010) and Chair of Presidential Council (2012-2015) of the Gastrointestinal Pharmacology Section of the International Union of Basic and Clinical Pharmacology and visiting and honorary professors of Peking University, Fudan University, Zhejiang University, Virginia Tech, University of Maryland, University of California and others. His current research interests focus on drug development for inflammation and cancers in the gastrointestinal (GI) tract. Professor Cho is the editorial board member and associate editor in more than 25 journals in the fields of Gastroenterology and Pharmacology.


Area of Interest

1. Pharmacological and toxicological role of trace elements, especially zinc in the gastrointestinal tract. 2 Pathogenesis of experimental ulcers and inflammation in the gastrointestinal tract, including those induced by ethanol, stress, nonsteroidal anti-inflammatory drugs and Helicobacter pylori. 3. The carcinogenic mechanisms of nicotine, nitrosamines and cigarette smoking on the gastrointestinal tract. 4. Drug development for gastrointestinal disorders, especially traditional Chinese Medicine and peptides.
