About Me

head_shot

I am a postdoc in the Princeton Neuroscience Institute, where I recently completed a PhD with Carlos Brody and Matt Botvinick. Very soon, I’ll be moving to London to work with Matteo Carandini and Kenneth Harris as well as DeepMind. My interests lie between neuroscience and artificial intelligence. I ask questions like “How can we understand what the brain is doing well enough to reproduce it in software?

My recent work has focused on understanding how the brain makes plans. This work involves training rats to perform multi-step structured games, and carefully studying both the choices that they make and the neural signals that underlie those choices. It also involves designing software agents that play the same games as the rats, and using these agents as tools for understanding the brain. Along the way, I have become interested in reinforcement learning, multi-level modeling, and the function of several brain regions, including the hippocampus, striatum, prelimbic cortex, and orbitofrontal cortex.

When I’m not in the lab, I can often be found hiking up a mountain, canoeing down a river, exploring a canyon, cross-country skiing, or otherwise enjoying the outdoors.
