Dr Derek Cheung is currently a Research Assistant Professor at the School of Nursing, The University of Hong Kong (HKU). He received his Bachelor of Social Sciences (Major in Statistics) and M.Phil. from HKU; and Ph.D. from the Melbourne School of Population Health in the University of Melbourne. 


Before joining the School of Nursing, he has received post-doctoral training in the School of Public Health of HKU, where he studied the effectiveness of various smoking cessation interventions including medication, counseling, brief advice, financial incentives and social media. He is experienced in designing and conducting randomized controlled trials in various community and clinical settings. He is currently the key investigator of several tobacco-related projects including opinion survey on tobacco control policy, use of smartphone Apps and exercise for smoking cessation, health promotion at smoking hotspots, and physician-delivered smoking cessation advice in the Guangdong province of China.


His research interests also include suicidal epidemiology and spatial analysis. His PhD thesis looked into the spatial-temporal clustering of suicides in Australia, suicide hotspots and the associated factors. He is now studying youth risk behaviors including non-suicidal self-harm, suicidal behaviour and substance use with in-school survey data. He has published more than 31 articles in peer-reviewed journals including The Journal of Pediatrics, Journal of Medical Internet Research, Social Science and Medicine, and Addictive Behavior.
