Prof. Kin-on KWOK

BSc (CUHK), MPhil (CUHK), PhD (HKU)



  • Honorary Lecturer, Department of Infectious Disease Epidemiology, Imperial College of Science, Technology and Medicine, United Kingdom​


Prof. Kin On Kwok joined The Jockey Club School of Public Health and Primary Care of the Chinese University of Hong Kong in 2016. He obtained his PhD degree in Public Health Medicine from the University of Hong Kong in 2008. He is currently the concentration coordinator of Environmental / Occupational Health and Infectious Diseases in the Master of Public Health curriculum. In addition to supervising graduate students, he currently teaches two courses including Biostatistics and Practical Data Collection, Management and Analysis in the undergraduate curriculum. In 2018 and 2019, he has been awarded with “Teachers of the Years Award” by Faculty of Medicine, CUHK. His main publications are on infectious diseases epidemiology, infection control of emerging diseases and dynamics model in infectious diseases. He is currently the principal and co-investigators for several ongoing local and international research projects funded by University Grants Committee, Food and Health Bureau and Wellcome Trust. He is also Deputy Section Editor of Virology Journal, Associate editor of Frontiers in Medicine/Public health/Sociology/Psychiatry and Plos One and Guest editor of Computational and Structural Biotechnology Journal and Vaccines.


During the COVID-19 pandemic, he had done more than 300 interviews by many international media including Ignites Asia, the New York Times, Bloomberg, Nature News, NTV Broadcasting Company (Russia) and numerous local media including TVB, Now TV, RTHK, Headlife and South China Morning Post on various topics related to infection control and epidemiology of COVID-19, influenza, and other infectious diseases.


My main research interest is to study Transmission dynamics of infectious disease; Infectious disease epidemiology; and Infectious disease surveillance, particularly in respiratory viruses including influenza virus and severe acute respiratory syndrome coronavirus (SARS-CoV), and antimicrobial resistance (AMR).  I am particularly intrigued by the development of mathematical transmission model and the use of statistical models in understanding infectious diseases epidemiology to inform infection control policies.
