Dr. Hein Min Tun

Principle Investigator

Dr Hein Tun is a public health veterinarian and received his Ph.D. degree from the University of Hong Kong. He then moved to Canada to pursue his postdoctoral research at the Gut Microbiome Laboratory of the University of Manitoba where he held an additional role as a lab manager.  After 2 years working for microbiome and resistome research in food animals, human and the environment, he joined with the SyMBIOTA research team at the Department of Pediatrics in the University of Alberta to study roles of infant gut microbiome in health and diseases using the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort.

His research interests range from studies on the role of human and animal microbiome in health and diseases to surveillance of antimicrobial resistant bacteria (resistome) in the interface of human, animals and the environment. His research findings have been frequently featured in major international media and also highlighted in Nature Outlook.

Dr. Hiu Laam Kathy, Po

Post-doctoral fellow

Dr. Po completed her Bachelor’s degree in Applied Biology with Biotechnology in 2013 and a PhD in Biological Sciences in 2020, both from the Hong Kong Polytechnic University. During her PhD study, she was mainly working on structure-function relationships of enzymes that mediate bacterial resistance to fluoroquinolone and beta-lactams. In other collaborative projects, she screened for various antibiotic analogues to discover novel antibiotics active against Gram-positive pathogens and depicted the mechanisms of enhanced activity.

Dr. Po joined University of Hong Kong in 2020 to receive postdoctoral training. Her current research covers surveillance of antimicrobial resistant bacteria in the interface of human, animals and the environment.

Mr. Dengwei, Zhang

Research Assistant

Dengwei received his Bachelor's degree, as well as Master's degree of biochemistry and molecular biology from University of Electronic Science and Technology of China (UESTC). After graduated, he worked at BGI for 3 years. His previous research interests involve plant genome editing, gene engineering and bioinformatics. He is now focusing on bioinformatics related to microgenomics.

Ms. Hilda, On

Research Assistant

Hilda graduated from the Higher Diploma student in Biotechnology at the Hong Kong Institute of Vocational Education (IVE).
She was a summer intern in HKU-Pasteur Research Pole, during which she was in charge of a project for sample collection and laboratory tests. After graduation, she joined the Tun Lab as a research assistant.

Mr. Alex, Wong

Research Assistant

Alex Wong earned his Bachelor's degree of Food Safety and Technology at the Hong Kong Polytechnic University in 2020. He is currently working on an AMR project about humans, animals, and the environment.

Mr. Hogan Wai

Research Assistant

Hogan received his MSc Biochemical & Biomedical Sciences degree from The Chinese University of Hong Kong. His research interests include gut microbiota and allergic diseases. 

Mr. Darren, Chan

Ph.D. Student

Darren received the degree of Bachelor of Science in the University of Hong Kong with Chemistry and Food & Nutritional Science as his majors. Afterwards, he received his M.Phil. degree in the University of Hong Kong. He studied the antimicrobial activities of natural antioxidants extracted from edible plants against different bacteria, including some common food-borne pathogenic bacteria.

Ms. Suisha, Liang

Ph.D. Student

Suisha received her Bachelor's degree in Biomedical engineering in Huazhong University of Science & Technology, Wuhan; Master's degree in Bioengineering in South China University of Technology (SCUT), Guangzhou. she worked as an intermediate bioinformatics analysis engineer at BGI-Research for more than 9 years before joining the Tun lab. Now she is a Ph.D. student studying the correlation between mental health and microbiome.

Mr. Ye, Peng

Ph.D. Student

Ye received his Bachelor's degree in Pharmaceutical Engineering (Biopharmaceutics), and Master's degree in Biochemistry and molecular biology in South China University of Technology (SCUT), Guangzhou. He had joined a SCUT-BGI joint-training project in his junior year, and been an intern in bioinformatics research of microbiome in health and disease at BGI-Research for more than 4 years. He is now Ph.D. student in the Tun Lab, majoring in microbiome bioinformatics.

Mr. Sze Wang, Li

Final Year Project Student

Sze Wang Li is a penultimate student studying under a Bachelors of Biomedical Science in The University of Hong Kong. He temporarily joined the team in the summer of 2019 as a summer research intern in studying the relationship of stress and the gut microbiome. Since then, he has returned in September 2020 as a Final Year Project student studying functional metagenomics to investigate novel antibiotic resistance.


Dr. Kanchana, Poonsuk

Post Doc (2018-2020)

Dr. Poonsuk is a veterinarian experiences in antimicrobial resistance research and animal production in South-East Asia. She has been worked in Center for Antimicrobial Resistance Monitoring in Foodborne Pathogens (in cooperation with WHO) and WHO Global Foodborne Infections Network: South-East Asia and Western Pacific Region (GFN) before enrolled her PhD in Veterinary Public Health, Chulalongkorn University. Her research interests are microbiome and antimicrobial resistance in human, animal and environment based on One Health concept.
