Dr. Manuel is a Medical Doctor with a Masters in Epidemiology and Royal College specialization in Public Health and Preventive Medicine. His research combines together in interests in public health, health care systems and primary care. Researchers at OHRI are international leaders in developing clinical risk prediction tools. His lab builds on OHRI strength by creating risk algorithms that can be used at the level of population, in the clinic setting, or by people outside the clinic setting (see These population risk tools are then used to assess the population health impact of strategies and interventions for improving health. For example, he research estimated Ontario’s population can gain seven more years in life expectancy and have a better quality of life if four health behaviours were eliminated (smoking, physical activity, alcohol and diet). He has written on how societies with the best population health have achieved their success.

Much of his research is based on data that links together population risks with health care delivery. OHRI and Ottawa have world-leading and unique infrastructure for his research, including The Ottawa Hospital Data Warehouse – likely the largest and best developed hospital-based research data system. The Ottawa based data are then linked to province-wide data at the Institute for Clinical Evaluative Sciences and the Ottawa Hospital Data Warehouse. He also performs research in collaboration with Statistics Canada, the Public Health Agency of Canada and other federal and provincial agencies, leveraging OHRI position as a leading institute with the national capital. His research includes the development of methods for using large linked health data systems. He assists other researchers and train new investigators whose research programs benefit from the use of population health and health care data – providing him with research collaborations with other Ottawa research institutes.


He has worked as a primary care physician in rural, remote and underserviced community across Canada for over 20 years. His current practice is at Wellness Centre, the health care point of entry for refugees arriving in Ottawa. Research
