System Microbiology & Antimicrobial Resistance @Tun (SMART) Lab
Faculty of Medicine, The Chinese University of Hong Kong

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.

​Dr. Ye Peng is a microbiome scientist specializing in the gut microbiome's role in early-life health and disease. He completed his PhD at the University of Hong Kong and received postdoctoral training at the Chinese University of Hong Kong, where his cohort studies revealed how perinatal exposures shape gut microbiota development and influence childhood obesity, food sensitization, immune responses to vaccines and colonization resistance against AMR bacteria. Dr. Peng's interdisciplinary research integrates multi-omics, epidemiology, and machine learning to advance microbiome science and combat antimicrobial resistance. His long-term vision focuses on defining "healthy microbiomes" and translating discoveries into personalized therapies to improve health from early childhood to aging populations.

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 at the University of Hong Kong, in which she obtained her Ph.D in Microbiome in Health and Disease.

Dr. Subhankar Mukhopadhyay is a pharmacist and microbiologist currently serving as a postdoctoral researcher at the JC School of Public Health and Primary Care, Faculty of Medicine, The Chinese University of Hong Kong. He earned his bachelor's degree in pharmacy from BCDA College of Pharmacy and Technology in Kolkata, India, before receiving a prestigious scholarship from the Chinese government to pursue a Master’s degree in Pharmaceutics at the China Pharmaceutical University in Nanjing, China. Dr. Mukhopadhyay specializes in pharmaceutical and microbiological research, focusing on antimicrobial resistance, innovative bacteriophage therapy, formulation science, novel drug delivery, and nanotechnology. He holds a PhD in Pharmacy from CUHK, awarded under the prestigious Hong Kong PhD Fellowship. Throughout his career, he has authored numerous articles in esteemed peer-reviewed journals and has successfully secured multiple grants to present his research at international conferences. Currently, he is dedicated to developing novel bacteriophage-based antimicrobial strategies to combat the growing threat of antimicrobial resistance.

Shilin graduated with a master's in Public Health from the University of Hong Kong and a
bachelor's in Health Inspection and Quarantine at Guangdong Medical University. He
worked as a data analyst before joining the Tun lab. His research focus is in
epidemiological methods and mental health.

Juelei (Jelly) received a Bachelor's of Medical Science (Hons I) in Immunobiology (anatomy/histology) and Microbiology (for honours) from the University of Sydney. She also received a Master's in Biomedical Sciences in Immunity and Infection from the same institution. She is now pursuing a Ph.D at the Tun Lab, focusing on elucidating the mechanisms underlying autism spectrum disorder. 

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.

Guanwen is a recent graduate of Zhejiang University, where he received his Bachelor's degree in Veterinary Medicine in 2022. He was an intern at Zhejiang Provincial Center for Disease Control and Prevention (ZJCDC) in 2020. During his undergraduate studies, his research mainly focused on Salmonella spp. Currently, he is now a PhD student in the Tun Lab, focusing on bacteriophage therapy and AMR projects.

Yuzhou received his Bachelor's degree in Biomedical Engineering at Beihang University (BUAA) in 2022; Master's degree in Biomedical Data Science at Nanyang Technological University (NTU) in 2023.
