Principal Investigator
Hein Tun is a public health veterinarian and 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 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 the resistome. His major research focused on the impact of the early-life exposome on the development of gut microbiome and the 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, and Gut Microbes. Moreover, he has received several international research awards and fellowships including the Gold Medal at 2021 Inventions Geneva Evaluation Days, Canadian Institute of Health Research Fellowship, and the Dik Zwart Award.

Ms. Xueqi Wu
Ph.D. Student
Xueqi received both her Bachelor’s degree and Master’s degree in Public Health Laboratory Sciences at West China School of Public Health, Sichuan University in 2020 and 2023, respectively. She has previously worked on gut microbiome dysbiosis in HIV-infected individuals. Funded by a prestigous Hong Kong PhD Fellowship Scheme(HKPFS), Xueqi is now a Ph.D. student in the Tun lab, where she is focusing on early-life environmental exposures on infants gut microbiome and related health outcomes.

Mr. Brian, Ho
Data Analyst
Brian received a BSc in Information Systems from the University of New South Wales and an MSc in Genomics from the Chinese University of Hong Kong. Prior to joining the Tun Lab, he worked on cancer genomics. He is now focusing on microbiome data analysis, AI and cloud computing.

Mr. Zhu, Jie
Research Assistant (Bioinformatics)
Zhu Jie received a BSc in Bioinformatics from Huazhong Agricultural University. His primary reserarch foci are in genomic and microbiome informatics. He is responsible for developing bioinformatics pipelines and data analysis.

Ms. Xin, Liu
Research Assistant
Xin Liu received a BSc in Bioinformatics from Hunan University and currently focuses on bacterial genomic analysis in the Tun Lab.

Mr. Zhen Ye (Daniel), Sin
Research Assistant
Daniel received his bachelor’s degree from the University of Durham, UK, where he majored in Biosciences. He previously joined the Tun Lab as a student intern during Summer 2019, where he studied the acquisition of antimicrobial resistance genes during travel abroad. After receiving his bachelor’s degree, he returned to the Tun Lab as a full-time research assistant. His research interests include the biochemical mechanisms that drive commensal persistence in gut microbiota and bacteriophages. He will soon pursue a Ph.D at Imperial College London to study bacteriophages.

Ms. Ingrid, Chan
Research Assistant
Ingrid graduated with a BSc in Microbiology from Imperial College London. In the Tun Lab, she has previously worked on antimicrobial resistance but is now focusing on gut microbiota determinants in association with depression and its modifiable effects.
