Research Interests

Mobility Matters!

Mobility encompasses the ability to walk and perform daily activities, to be physically active, and to participate in society. Mobility fosters wellbeing, purpose, and connectedness. Unfortunately, mobility limitations are common among older adults and have profound negative impacts on independence and quality of life. Major sources of mobility limitation include fall-related injuries, lack of physical activity, and fatigue during daily activities.

In Dr. Mackey’s Aging and Population Health Lab, we are committed to conducting clinical research on mobility and aging to ensure healthy aging for all Canadians and the sustainability of the nation’s health care costs. Our research generates new insights about the cause, prevention, and management of age-related mobility limitations, which we translate with our partners, into new strategies to improve mobility for older Canadians.

Research in the Aging and Population Health Lab incorporates methods and techniques from epidemiology, biostatistics, and knowledge translation. These include clinical trials, feasibility and proof-of-concept studies, longitudinal cohort studies, causal inference, laboratory experiments, qualitative inquiries, knowledge synthesis, meta-analysis, and formative evaluation.

Our Mission: To enable mobility in older adults.

Training Opportunities

Graduate Students and Post Docs

Dr. Dawn Mackey welcomes applications from prospective MSc and PhD students from a range of backgrounds including kinesiology, human kinetics, exercise physiology, physiotherapy, occupational therapy, public health, knowledge translation, biostatistics, and epidemiology.

Dr. Mackey is an Associate Professor at SFU in the Department of Biomedical Physiology and Kinesiology, a Michael Smith Foundation for Health Research Scholar, a core member of the UBC Centre for Hip Health and Mobility, and an Associate Member of the Department of Gerontology at SFU. Through these affiliations, trainees have access to a wide variety of valuable and high-level training resources.

Dr. Mackey is currently accepting applications for graduate students in two main areas.

  1. Core Outcome Sets for Physical Activity Trials. This project will use knowledge synthesis techniques and consensus building exercises toward the definition of standardized sets of outcome domains for physical activity trials.
  2. Physical Activity Adherence. This project will determine the effects of physical activity promotion interventions on uptake and adherence to regular physical activity among inactive older adults.

If you are interested and qualified, please contact Dr. Mackey via email at dmackey@sfu.ca with your areas of interest, current curriculum vitae, and academic transcripts. Positions will be available until filled. Start dates are flexible.
