Dr. Paterson’s research is focused on the cardiovascular system and muscle metabolism in response to exercise, and in particular the oxygen uptake kinetics.  Some studies focus on older subjects and age-related changes in the exercise response.  Exercise training and chronic adaptations in cardiovascular, respiratory, and muscle metabolism are also of interest.   Additionally, studies have been carried out to explore the interrelationships of cardiorespiratory fitness and activity with quality of life (and morbidity) in the elderly. Dr. Paterson is currently serving as the Research Director of the Canadian Centre for Activity and Aging.

MSc (Waterloo), PhD (McMaster)
Professor, School of Kinesiology, Faculty of Health Sciences

Dr. Kowalchuk’s interests are centered around cardiovascular, respiratory and metabolic adaptations and control with exercise and ageing. He studies the mechanisms determining the rate of adaptation of O2 uptake and blood flow following a sudden change in energy requirement in young and older adults using: breath-by-breath techniques for measuring gas exchange (O2 uptake; CO2 output); near-infrared spectroscopy to measure muscle oxygenation; Doppler ultrasound techniques for measuring central and peripheral beat-by-beat blood flow; computer modeling to study the time course of adaptation of gas exchange and blood flow; and blood sampling, muscle biopsy and magnetic resonance spectroscopic techniques for studying muscle metabolism.

Lab Technician

brad hansenBrad Hansen

Brad joined the Health Sciences team in 1992 as the chief laboratory technician. Since then he has proved to be an invaluable member of the Health Sciences research team at UWO. This is Brad’s final summer at the University of Western Ontario and he will be dearly missed as both a friend and co-worker. Best of luck, Brad!

Graduate Students

Andrea Marjerrison, PhD Candidate

Andrea is currently a PhD candidate at the CCAA under the direction of Dr. John Kowalchuk. She completed her undergraduate degree in Kinesiology at Brock University, followed by a Master’s degree at Ball State University in Muncie, Indiana. She is currently at UWO working on a project designed to examine the contribution of respiratory muscles to exercise. In her spare time Andrea enjoys competing in sporting events including her first half ironman this summer.

matt spencerMatt Spencer, PhD Candidate

Matt Spencer began his doctoral studies in cardiovascular exercise physiology under the supervision of Dr. Donald H. Paterson in September, 2007. After completing his undergraduate degree (BSc. in Human Kinetics) at St. Francis Xavier University in his hometown of Antigonish, NS, he earned a M.Sc. in Kinesiology from the University of Saskatchewan before spending two years as an instructor back at StFX. His research primarily focuses on the metabolic and cardiovascular responses to exercise during the transition between work rates with a particular interest in the rate of adjustment in oxygen consumption and muscle deoxygenation. Since 2009, Matt has been an assistant coach with the UWO women’s basketball team.

Kaitlin McLay, MSc Candidate

Kaitlin was raised on a family farm on the Bruce Peninsula near Lion’s Head, ON.  She studied Biological Sciences at the University of Guelph before coming to Western in September 2010.  She is currently working towards an MSc degree under the supervision of Dr. Donald H. Paterson, and is studying the acute effects of resistance training on VO2 kinetics and flow-mediated dilation in both young and older adults.  In her free time Kaitlin enjoys spending time with friends and family, traveling, and a variety of outdoor activities, such as horseback riding, hiking and canoeing.

Alex Williams, MSc Candidate

Alex is currently a second-year Master’s student in the CCAA’s cardiovascular lab, under the supervision of Dr. John Kowalchuk. She completed her undergraduate studies here at Western in 2009, graduating with a Bachelor of Medical Science (Honors Physiology) degree. Her current research is examining the effects of high intensity interval training on the rate of oxygen uptake at the level of the muscle in young men, with a particular interest in the speeding of oxygen kinetics at lower and higher metabolic rates, and how responses at those two levels may or may not differ.
