Description of Research Expertise

My research focus is on the characteristics and limits of functional neuroplasticity in the adult human brain. I investigate how the brain reorganizes itself in response to injury, and whether or not it is possible to enhance the brain’s potential for reorganization in order to speed rehabilitation using noninvasive electrical or magnetic brain stimulation. A second area of interest for me is on the use of noninvasive brain stimulation to elucidate and enhance mechanisms of cognition in healthy individuals, and the biological, social, and ethical implications of neural enhancement.

Description of Clinical Expertise

I principally treat patients suffering from dementia. I also have expertise in evaluating and treating patients with cognitive deficits following stroke.

Description of Other Expertise

I am is deeply involved in issues related to diversity in medicine, inclusion, and health equity. I am one of the Assistant Deans for Diversity and Inclusion at the Perelman School of Medicine and I am the Vice Chair for Diversity and Inclusion in the Department of Neurology at the University of Pennsylvania.
