My research focuses on human learning and memory. I approach these topics from a cognitive neuroscience perspective with the goals of understanding the characteristics of mental processes and how they are realized within the brain. Most of my current research uses measures of brain electrical activity (ERPs) to study the brain processes that underlie recognition memory. In particular, ERPs are being used to dissociate the influences of recollection and familiarity on recognition memory. Other ongoing research, in collaboration with the Perceptual Expertise Network, uses ERPs to investigate the manner in which visual object recognition processes are influenced by expertise.
