Research Interests

Dr. Manuel's research combines his interests in public health, health care systems and primary care. The overarching question that spans his research is how to most effectively improve health of communities and reduce inequities. He is interested in assessing the real world effectiveness of strategies and interventions. He performs two types of studies: modelling studies or "what if” studies that examine the potential impact of interventions; and, observational or "what is" studies that examine the actual impact of interventions that are provided routinely in our society or that are experimentally being tested. His studies typically focus on prevention such as immunization and healthy living. His lab also performs supporting studies that describe or predict the future health of Canadians and health care use.

Brief Biography

Dr. Manuel is a Medical Doctor with a Masters in Epidemiology and Royal College specialization in Public Health and Preventive Medicine.

He completed his medical degree at Dalhousie University and then worked as a general practitioner in northern and remote communities across Canada. At age 26, he was the chief of staff of the hospital at Churchill, Manitoba serving the remote Inuit communities that lined the eastern shore of Hudson Bay. He came to realize during these years that to truly make an impact on the health of his patients he needed to address underlying, preventable causes. He returned to study public health and epidemiology at the University of Toronto. During his residency training he began his research career, which continues to address the same themes that arose during his earlier clinical practice.

His current practice is at the Ottawa Newcomer Clinic Centre, the health care point of entry for refugees arriving in Ottawa. He has published over 150 research papers, including papers in leading journals such as the New England Journal of Medicine and the British Medical Journal. He has held a Chair in Applied Public Health from the Canadian Institute of Health Research and has led public health research programs.

His life expectancy is 92.3 years and, according to, over his lifetime he will breath 1.3 million litres of air. He consumes 3400 mg of sodium per day. His favourite physical activity is biking to Champlain Lookout at Gatineau Park.
