My general research focus is the role of physical activity in successful aging. Specifically, I am interested in aging and hormonal responsesto exercise such as the influence of age on endogenous anabolic hormone levels, anabolic hormone responses to different types of exercise,
and the role of anabolic hormone levels in successful aging. Other interests include the measurement of physical activity behaviour, using both self-report tools and direct measurement tools such as accelerometers and pedometers.

Through collaboration with colleagues I have been involved in several other projects outside my main area of research. Most recently I was a co-investigator on two projects which measured fitness and physical activity in Old-Order Mennonite and Amish children in Southwestern Ontario. The objective of these innovative projects were to study the behaviours of those who adopt lifestyles somewhat representative of several generations ago, when current health concerns of obesity, diabetes, and heart disease were much reduced.
