Dr. Fong conducted research on the effects of alcohol intoxication on risky health behaviours (e.g., risky sex), and on the creation, implementation, and evaluation (using randomized controlled trials) of behavioural interventions to reduce HIV/STD risk among inner-city adolescents, before focusing on tobacco control. The mission of the ITC Project is to conduct rigorous evaluation of the psychosocial and behavioural effects of national-level tobacco control policies of the Framework Convention on Tobacco Control, the first-ever international treaty on health. In all, the ITC Project is conducting large-scale annual prospective cohort surveys of tobacco use to evaluate FCTC policies in countries inhabited by over 50% of the world's population, 60% of the world's smokers, and 70% of the world's tobacco users. The ITC Project is playing a role in establishing the evidence base for the FCTC. According to SciVal, the world’s most extensive research performance metrics system, Dr. Fong is the most productive researcher in the world in tobacco research, and 6 of the top 10 most productive tobacco researchers are members of the ITC Project.
