I am a research associate in the Department of Neurology at the University of Pennsylvania in Philadelphia. My resesarch focuses on the way in which variability in brain structure leads to different perceptual and cognitive abilities throughout the lifespan. To examine this broader issue, I make use of behavioral testing and brain imaging methods to study speech and language processing in the human brain, with a special focus on changes seen in both normal aging and dementia. Because of my interest in speech, I am also interested in auditory processing, and the way in which various changes in the auditory system (such as age-related hearing loss) affect the brain regions needed for understanding spoken language.
