Sam Liu, PhD, RKin

Institute of Medical Science, University of Toronto

Registered Kinesiologist




Dr. Liu received his doctoral degree from the Institute of Medical Science, University of Toronto. He is an eHealth researcher and a registered Kinesiologist. As an eHealth researcher, he studies how communication technology (e.g., Internet-based programs, mobile apps) can be used effectively to improve health and health services. His research focuses on three main areas: 1) evaluating the effectiveness of eHealth programs, including a randomized controlled trial on the effectiveness of an Internet-based intervention to promote blood pressure management; 2) understanding the critical components that make an effective Internet-based intervention, such as a study exploring the influence of expert- versus user-driven Internet-based intervention in reducing cardiovascular risks; 3) investigating strategies to promote usage and engagement with eHealth programs, including a study that investigated the use of loyalty rewards in promoting engagement with an Internet-based heart health program.


Dr. Liu is also an alumni Doctoral Fellow of the Canadian Institutes of Health Research Strategic Training Program in Health Care, Technology, and Place. He has received several research awards including the Heart and Stroke Doctoral Award, the CIHR Health Care Technology and Place Fellowship, and the Dr. Terry Kavanagh Fellowship. 


As a registered Kinesiologist, Dr. Liu is an expert in exercise training and prescription. He is particularly interested in understanding the optimal amount and type of exercises that will promote maximal health gains for individuals of various age, gender and health status. He has applied what he learned from research to help create personalized exercise training program tailored to children, as well as adults for coping with various health conditions such as heart disease, diabetes, and metabolic disorders.


Finally, Dr. Liu has a strong passion for knowledge dissemination. He is actively involved in teaching at the University of Toronto, as well as in a community-based science program for kids called Let’s Talk Science.
