Neural Mechanisms Underlying Attention and Visually-guided Actions

The long-term goal of my research is to elucidate the neural mechanisms underlying attention and visually-guided actions, including eye movements and reaching movements. To pursue this goal, my laboratory uses a range of techniques: performing psychophysical studies, investigating neural correlates, and testing causal relationships between activity and behavior. Areas of the brain of particular interest include the superior colliculus and frontal cortex.
