I began in psychology and worked in a visual neurophysiology as an undergraduate. I then completed a series of degrees in electrical engineering, doing graduate work in a computer vision and robotics lab. My work in graduate school was some of the early work in the field of computational neuroscience.

My main interest through the years has been in understanding how we see — understanding the neural circuits and dynamics that underlie how the brain assembles the most probable interpretation of what is out there in the visible world. Recently I have been examining the question of how we dynamically assemble the brain networks required to perform a cognitive task. We are using perceptual techniques developed in our lab in combination with functional MRI and magneto-encephalography to understand the brain networks and their temporal dynamics.

In addition to my long standing interest in vision, I have recently been working on understanding sports-induced traumatic brain injury via a mix of modeling and experiments. This is collaborative work with a group of experts in mechanics and materials, neuroscience and medicine. My personal interests include squash, skiing, sailing, and reading.
