Research interests

Physical activity and health research is an area of fundamental importance. Therefore, my research program focuses onto two major research themes:

Basic exercise physiology: Although it is widely accepted that exercise training prevents and counteracts many of the disease processes that contribute to chronic disease, researchers still do not fully understand the biological mechanisms to explain how physical activity promotes health. With this in mind, my research program utilizes exercise physiology as a tool to identify novel therapeutic targets and signaling pathways that regulate cardiovascular and skeletal muscle health. In order to do so, my research program utilizes isolated cell models, animal models as well as human volunteers to conduct a physical activity-based physiology research program. Specifically, we have focused particular attention to study processes that are activated by physical activity to regulate calcium transport proteins and muscle metabolism in models of health and disease.

Clinical exercise physiology: Sufficient physical activity is a prerequisite for health. However, 85% of Canadian adults do not accumulate enough physical activity on a weekly basis to achieve health benefits. This statistic is alarming because the Public Health Agency of Canada estimates that physical inactivity contributes to the development of 25 different diseases, including diabetes, heart disease, stroke, cancer and mental disorders. With this in mind, my clinical research program seeks to better support the utilization of physical activity as a health intervention. To facilitate this clinical research program, I have created links with the Winnipeg Regional Health Authority, the regional cardiac rehabilitation programs at the Reh-Fit Center and the Wellness Institute at Seven Oaks Hospital, the Cardiovascular Health and Research in Manitoba (CHaRM) Investigator group at the St. Boniface Hospital and the Health, Leisure and Human Performance Research Institute at the University of Manitoba. As an example, my clinical research program has conducted prospective, observational trials examining the relationship between physical activity and mental health after cardiac surgery amongst a cohort of 450 patients. My research program has also conducted an integrated knowledge translation project examining the development and implementation of a model physical activity promotion program within primary health care, which we commonly refer to as the ENCOURAGE project. Notably, the ENCOURAGE project has helped participants to re-schedule their lives in a manner that enabled them be physically active for 100 minutes more per week than they were before.

Trainee research placements

I enjoy providing students with opportunities to learn more about what it means to be a "researcher." In my own laboratory, I have been the primary mentor for two high school, 16 undergraduate, two B.Sc. Medicine, 11 Masters and two Doctoral students, as well as one visiting scientist since 2008.  I have also co-advised two Doctoral and one B.Sc. Med student. I do my best to provide an outstanding training environment for my student trainees by providing trainees with an opportunity to make meaningful contributions to the overall management of each project. I also enable students to interact with our research partners and stakeholders to inform best practice. Finally, I seek to tailor each research placement so the experiences gained fit within the student’s long-term career plan. Students with an interest to learn more about a research placement in my group can contact me by email.
