Research and Teaching Interests:

My interests revolve around vision and visual perception. Specifically, I have focused on 2 questions: What are the neural mechanisms underlying the allocation of visual attention and how are moving stimuli encoded and remembered in the brain. To answer these questions, I work with animals that are trained to perform simple behavioral tasks. I then use techniques such as single unit recording, reversible inactivation, microstimulation and long-term lesion studies. Recently, I have been studying the responses of neurons in posterior parietal cortex, while the animals perform under naturalistic viewing conditions. I am also running experiments that are aimed at understanding how information about visual motion is stored in short-term memory tasks. Finally, I have a continuing study aimed at understanding distractions based on a hierarchal model of the attentional allocation system.
