Research areas

My research encompasses three topics: neuroimaging, vision, and computation. I develop advances for neuroimaging that combine both electroencephalographic (EEG) and functional magnetic resonance imaging (fMRI). I utilize these neuroimaging techniques to study the computational mechanisms that visual cortex utilizes for information processing. I am especially interested in how the brain modulates its information processing to optimally respond to variations in the environment caused by both changes in stimulus properties and by changes to behavioral goals. My research interests also include studying the impact of neurological dysfunction on visual processing (e.g. epilepsy).
