I am a postdoctoral researcher with the Vision & Cognition Group at the University of Washington. I use the techniques of experimental psychology and cognitive neuroscience to study visual perception.

The big question is: How does the brain use the information streaming in from the eyes to selectively reconstruct elements of the outside world? Over the last decade I have been primarily interested in the perceptual effects of feature-based attention, covert spatial attention, and oculomotor control.

Currently, I am investigating visual word recognition: How many words can your brain process at once? How does dividing attention over multiple words impair recognition?

I use a combination of psychophysics, computational modeling, and functional magnetic resonance imaging (fMRI) to answer these questions, in collaboration with Dr. Geoffrey Boynton and Dr. John Palmer. In a related project with Dr. Jason Yeatman, we are investigating visual and attentional functions in children with dyslexia.
