Research & Publications

I generally frame my research program as the measurement, determination, and epidemiology of mobility disability and participation of older adults. More recently I’ve begun to target interventions to improve mobility, social participation and ultimately quality of life. Many of these interventions emphasize increasing mobility self-efficacy which mediates social participation.
