Dr Horace Choi obtained his PhD from the School of Public Health at The University of Hong Kong. His research interests cover health economics, infectious diseases modelling, effectiveness of cancer treatments and cancer epidemiology. He worked intensively on modelling the infection of human papillomavirus (HPV) and its development to cervical cancer using a dynamic transmission model between females and males. The outcomes linked to the cost-effectiveness analysis (CEA) of HPV vaccination and cervical screening for females in Hong Kong. Dr Choi also conducted various cancer research analyses, with particular foci on nasopharyngeal and gastrointestinal cancers, including multi-center clinical trials, CEAs of targeted therapy and immunotherapy, quality-of-life studies and network meta-analyses.
