Academic Interests

Dr. Teo is a clinician/researcher whose academic interests lie in contributing to the education of clinicians in the Health Research Methodology program.

Dr. Teo's research interests are in clinical trials and epidemiology studies on cardiovascular diseases. He is the principal investigator and in major studies supported by the CIHR and other funding agencies. These include the FAMILY study and COURAGE trial. The FAMILY study has recruited and is following 859 families with 901 babies investigating the origins of atherosclerosis and cardiovascular risk factors in early life and the influences of environmental and genetic factors in shaping future cardiovascular disease. The COURAGE trial, of which he is the Canadian PI, showed that in individuals with stable coronary disease and angina, long term intensive medical therapy is as good coronary ballooning and stenting plus intensive medical therapy. This finding is having a large impact on the practice of cardiology. He is Co-Investigator for the PURE epidemiology study in 17 countries enrolling over 140,000 subjects studying the causes of cardiovascular risk factors in various societies and communities.
