I am a fifth-year PhD student working with Dr. Philip Thomas in the Autonomous Learning Lab (ALL). My research interests lie at the intersection of reinforcement learning (RL), stochastic neural networks (coagent networks), deep learning, and robotics. I am particularly interested in "sim-to-real" transfer learning for RL with robotics applications. I am also interested in the intersection of RL and evolutionary algorithms/AutoML.
