Andrew Perrault

I am an assistant professor in the Department of Computer Science and Engineering at The Ohio State University. My research focuses on reinforcement learning and optimization and their application to scientific and engineering problems.

I was a Postdoctoral Fellow with Milind Tambe at Teamcore at the Center for Research on Computation and Society at Harvard. I completed my PhD in September 2018 under the supervision of Craig Boutilier at University of Toronto.
