MAIN RESEARCH INTERESTS
Professor Lam’s research interests are on epidemiology and control of noncommunicable diseases with a major focus on tobacco and other lifestyle related diseases.  He is/was principal investigator of several major epidemiological studies, including the Hong Kong Lifestyle and Mortality Study (40,000 subjects), Guangzhou Occupational Cohort Study (160,000 subjects), Hong Kong 1997 Birth Cohort Study (8,300 subjects), Hong Kong Elderly Health Services Cohort Study (60,000 subjects), Guangzhou Biobank Cohort Study (Co-PI 2003 to present; 30,000 subjects) and FAMILY project (A Jockey Club Initiative for a Harmonious Society; donation HK$250 million).  As principal investigator of FAMILY project, he collaborated with several hundred social service, health related and community organisations and schools on many community-based projects to promote family health, happiness and harmony (3Hs) based on public health approaches and positive psychology with vigorous evaluation.  In FAMILY project Phase 2, he initiated “Zero Time Exercise” as a new approach to promote physical activity since 2014.  Because of the zero wine and beer tax in Hong Kong since 2008, he has been involved in alcohol control and related research.  He has published 950+ papers in international peer reviewed journals.  He was principal investigator (2018-21) of the Jockey Club Smart Family Link Project (donation HK$157 million) using information communication technology to enhance family services and well being in Hong Kong.  He is committed to research on simple interventions to promote smoking cessation, alcohol control, healthy eating, healthy weight, physical activity (zero time exercise) and mental health.

ACHIEVEMENTS IN TOBACCO CONTROL
Professor TH Lam is one of the world's leading scientists and advocates on tobacco control.  His scientific contributions have been translated into important benefits to public health and tobacco control locally and internationally.  Since his first major paper on smoking, passive smoking and lung cancer in 1987, he has published about 260+ papers on tobacco control related areas in international peer reviewed journals.  He has contributed to four WHO reports, on secondhand smoke and child health, policy recommendations for smoking cessation, adherence to long term therapies, and smokefree policies, and one IARC report on reversal of risk after quitting.  He was the lead researcher of 100+ research projects and his publications cover a wide range of important areas, including health hazards and economic costs of smoking and passive smoking, youth smoking, role of health professionals in tobacco control and training, smoking cessation (especially brief interventions and randomised controlled trials), public opinion and policy surveys, evaluation studies and e-cigarettes and other new tobacco products.  He was actively involved in the campaign for the total ban on e-cigarettes and new tobacco products in Hong Kong, which has taken effect since April 2022.  He advocates for a total ban of all forms of tobacco and smoking in Hong Kong in 2030.
