Aging and Population Health Lab Member,
Centre for Hip Health and Mobility
Research in the Aging and Population Health Lab investigates the prevention, etiology, and management of age-related mobility impairment and disability. This includes the study of acute events such as falls and osteoporotic fractures as well as chronic processes such as fatigue and impaired gait energetics. Research in the lab incorporates techniques from epidemiology, biostatistics, energetics, and clinical research. Ultimately, our research seeks to identify and disseminate effective strategies for successful population aging through maintenance of mobility and functional autonomy.
Primary research interests of the lab include:
- Role of energy utilization and fatigue in the development of mobility limitation
- Interventions to reduce disability and injury and improve mobility
- Prevention and treatment of osteoporotic fractures, falls, and fall-related injuries
- Physical activity adherence and promotion
- Novel methods to objectively measure activity patterns in epidemiologic studies
- Development and testing of clinical assessment tools
- Longitudinal cohort studies, clinical trial design, causal inference
- Knowledge synthesis, systematic review, and meta-analysis

I am currently recruiting trainees who are interested in pursuing graduate research, undergraduate research, or co-operative education work terms in the lab. If you are interested, please feel free to contact me by phone (778) 782-9330 or email email@example.com
It is highly recommended that potential graduate students apply for external sources of funding for their research (e.g., MSFHR, CIHR, NSERC) as well as departmental Graduate Fellowships. Outstanding SFU undergraduates are encouraged to apply for an NSERC Undergraduate Student Research Award. Please contact me well in advance of these funding deadlines to discuss your interests and background and to allow adequate time to develop a funding proposal.
Additional information concerning graduate studies can be found on the SFU Department of Biomedical Physiology and Kinesiology Graduate Studies web page.
