I’m interested in understanding the neural correlates of value- based decision-making and executive control. Most of my research involves analysis of single-neuron data recorded in primate prefrontal cortex.

What Got You Interested in Research?
My undergraduate background is in computer science, and I’ve had a long-held interest in psychology and philosophy. I was especially interested in concepts of self-control, self-determination and free will, but wanted to tackle these from a primarily scientific perspective. My ultimate goal is to understand the algorithms and biological circuits that enable us to exhibit such complex, motivated behavior.
