Professor Zhou was jointly appointed by the Department of Family Medicine and Primary Care (host department), the Department of Pharmacology and Pharmacy, and the School of Public Health at the HKU LKS Faculty of Medicine in 2024. He earned his PhD in Data Science from the School of Data Science, City University of Hong Kong, and received his post-doctoral training as a Medical Statistician at the Nuffield Department of Medicine, University of Oxford, United Kingdom. Before joining HKU, Professor Zhou worked as Assistant Professor at Warwick Medical School, University of Warwick, United Kingdom.

Professor Zhou has research interests in big data analytics, medical statistics, primary care and preventive health, case-control and cohort studies, predictive and decision analytics, pharmacoepidemiology and aetiology of chronic diseases (including cardiovascular diseases, diabetes mellitus, etc. for family medicine patients). He has study interests in casual treatment effects analysis (double machine learning), social epidemiology and adverse online events identification with text mining, high-dimension data representation and latent cluster pattern learning in large-scale health datasets. Recently, he is conducting machine learning analytics for illness trajectories and palliative care, especially progression pattern analysis/visualization, end stage risk accessment following chronic diseases, and non-invasive cancer screening.
