The long-term goal of research in my lab is to elucidate the neural mechanisms underlying attention and visually-guided actions, including eye movements and reaching movements.

To pursue this goal, we use a range of techniques: performing psychophysical studies, investigating neural correlates using multi-electrode single-unit and local field potential recordings, and testing causal relationships between activity and behavior using pharmacological and electrical manipulations of neural activity.

Areas of the brain of particular interest include the primate superior colliculus and frontal cortex (FEF, PMd, PFC). Through collaborations, I am also involved in studies of deficits in attention and visually-guided actions in patients with focal brain damage.
