• Pediatric Exercise Science

I am always happy to hear from prospective students with an interest in children and exercise.  I am looking for students who have experience working with children and can demonstrate research skills, particularly students who have completed 4th year or MSc theses. We have a great team of undergraduate students, MSc and Ph.D. students, as well as research associates. Students can get involved in one of the above areas of research, or develop their own study, involving children and exercise.

If you think you would be a good addition to our lab, I encourage you to read about our research projects and publications, then contact me with an outline of your academic background (current degree and topic, average grades, and research experience), general interests, and perhaps specific ideas about potential projects, interests, and if you wish, specific ideas you would like to focus on.

I accept applications from prospective undergraduate students wishing to participate in our research. Students wishing to conduct independent projects or a thesis (e.g., KINE 3P99, 4P99, 4F91) are especially encouraged to apply. A mark ≥ 80% in Growth and Development (KINE 2P84), as well as a background in data management and statistics, are assets. Prospective students with the appropriate background are invited to read about our research projects and publications and e-mail me a short message outlining their academic background (current year, program, relevant course, research experience, and an unofficial transcript), and their availability for research during the school year and in the summer (Please send only .pdf files).
