John Luoyu Zhou
Hello! I'm a Computer Science Ph.D. student at UCLA, advised by Jonathan Kao. Previously, I received my B.S. in Computer Science from Columbia University, where I was advised by Liam Paninski in the Center for Theoretical Neuroscience.
My current research interests involve the recursive decomposition of complex, long-horizon tasks into simpler subproblems. I view hierarchical learning as both a structural prior that improves optimization in reinforcement learning and a framework for continual learning of increasingly sophisticated skills.
Previously, I also spent some time studying computational neuroscience, investigating how the brain allocates control between model-free and model-based decision-making strategies and developing neural decoding methods for brain-computer interfaces.
