Bio
I lead the Brain, Environment, Aging, and Mobility (BEAM) lab. My research aims to improve function of older adults, reducing disability and helping individuals stay independent in their communities. I use an inter-disciplinary approach to understand how aging, and particularly brain aging, affects an individual’s ability to navigate the complex community environments that we experience every day and to understand how community environments shape brain aging. My research combines advanced methodologies in neuroimaging, gait analysis, neighborhood assessment, and longitudinal epidemiology to determine mechanisms of functional decline, both physical and cognitive, and inform future intervention research.
