My Research
I have long been interested in the interface between perception and cognition. My research has so far investigated this topic in the visual domain, which, at least for sighted individuals, is a critical part of everyday experience and behavior.
Specifically, I have been pursuing questions about how visual perception, attention, and working memory interact to ultimately influence human behavior and subjective experiences. To do this, I take advantage of a variety of techniques, including behavioral measures, psychophysics, eye tracking, and EEG/ERP.
The ability to coordinate goals, perception, and action clearly has an enormous impact on mental health and quality of life. A significant portion of my work aims to understand individual differences in such attentional functioning. To address this, I have been investigating the nature of impairments in schizophrenia, which has been associated with both perceptual and cognitive dysfunction. A better understanding of how information processing is mediated across networks in the brain will help lead to the development of more effective treatments for schizophrenia and other disorders.
