Daniel Tzu-Hsuan Chen

Daniel is a research fellow in the Primary Care Epidemiology Group in the Nuffield Department of Primary Care Health Sciences at the University of Oxford. With a background in rehabilitation medicine and epidemiology, his research focuses on non-communicable disease prevention, particularly smoking and tobacco use, cardiovascular diseases, and cancer prevention. Daniel's work uses large-scale datasets and routinely collected health records to understand population health and help shape healthcare policies.

Daniel is passionate about improving public health outcomes through evidence-based research and policy development. He has published manuscripts on tobacco prevention and smoking cessation using national datasets, cancer epidemiology, and COVID-19 vaccination safety and efficacy studies for vulnerable populations, such as immunocompromised individuals and those with blood cancer, using the QResearch primary care database.

Currently, Daniel leads projects funded by Cancer Research UK, examining antibiotic use and survival in cancer patients, particularly those with breast and colorectal cancer. He is also leading data analysis on therapeutic uptake in blood cancer patients to improve healthcare policy. Additionally, he is involved in lung cancer epidemiology projects, focusing on inequalities in treatment, diagnosis, and health outcomes.

Daniel earned his PhD in Clinical Medicine Research (Public Health) from Imperial College London, where he conducted research on tobacco control and the global epidemiology of poly-tobacco product use. Originally from Taiwan, he holds an MSc in Rehabilitation Medicine from National Taiwan University. Prior to his PhD candidature, he practiced as a licensed physiotherapist in Taiwan and worked in academic, non-governmental, and industrial settings as a public health scientist.
