Personal profile
Research interests
Brain, gait and cognitive decline in aging and preclinical dementia; social dancing; social connection; social isolation; social networks and support, loneliness; mild cognitive impairment; motoric cognitive risk; Alzheimer’s disease and related dementia.
The overall goal of my research is to optimize social, cognitive and physical functions in aging and early dementia. I design, analyze, interpret, evaluate, and publish studies examining social connection, cognition, and gait in aging and preclinical dementia, using cognitive, neuropsychological, clinical, epidemiological, and neuroimaging methods. I have an established publication record in the areas of social connection, cognitive and motor aging, and neuroimaging (particularly MRI).
