Dr Derwin Chan is an expert of sport psychology, health psychology and behavioural medicine. He was an elite triathlete in Hong Kong before having his education and training from the UK. Following the completion of his PhD from the University of Nottingham in 2012, Derwin worked as a psychology researcher in the School of Psychology and Speech Pathology at Curtin University (Australia). In 2015, he joined the University of Hong Kong as an assistant professor of sport psychology at the School of Public Health. Derwin’s research looks at the psychological processes underpinning a broad range of human behaviours, such as sport, anti-doping, treatment compliance, and preventive actions. Derwin is a chartered psychologist and an associate fellow with the British Psychological Society and a Chartered Scientist with British Science Council. Derwin’s research primarily focuses on psychosocial, motivational, and social cognitive processes underpinning individuals’ health behaviours, including (but not exclusive to) sport and exercise, treatment adherence, and the prevention of work-related injury (e.g., sport/ occupational injury), deficiency (e.g., myopia), diseases (e.g., influenza), and illegal substance-use (e.g., doping in sport). In addition, Derwin is keen to examine the relative influence of significant others (e.g., coach, parents, physicians, and physiotherapists) in the area of sport and other healthcare contexts. Dr Chan’s research primarily focuses on psychosocial, motivational, and social cognitive processes underpinning individuals’ health behaviours. He develops evidence-based digital health interventions in a number of health contexts, such as injury and disease prevention, safety in sport, and anti-doping. He has attracted competitive research funding, as principle investigators, from governments (e.g., General Research Fund, Health and Medical Research Fund), local funding bodies (e.g., Hong Kong Jockey Club), and international organisations (e.g., World Anti-Doping Agency). In recognition to his expertise in sport medicine, health psychology, and sport psychology, Dr Chan has been invited serve important roles in the editorial boards of a number of scientific scholarly journals.
