Dr. Hein Min Tun

Principal Investigator

Hein Tun is a public health veterinarian, currently an Associate Professor at the JC School of Public Health and Primary Care, Faculty of Medicine, the Chinese University of Hong Kong. He is also an Adjunct Professor at the Nanjing Medical University and an Adjunct Associate Professor at the University of Hong Kong. His research interests range from studies on the mechanistic and functional roles of microbiome in health and diseases to One Health surveillance of antimicrobial-resistant bacteria and resistome. His major research focused on the impact of early-life exposome on the development of gut microbiome and associated risks for allergic, metabolic and immune-mediated diseases. He is the young scientist member of the Scientific Steering Committee of the Pasteur Network. He has published more than 75 original peer-reviewed articles in high impact journals such as Gut, Gastroenterology, Nature Communication, Microbiome, JAMA Pediatrics, Journal of Travel Medicine, Environment International, Gut Microbes etc.  Moreover, he received several international research awards and fellowships including the Gold Medal at 2021 Inventions Geneva Evaluation Days, Canadian Institute of Health Research Fellowship and Dik Zwart Award.
