Joewie J. Koh

PhD student at the University of Colorado Boulder and NSF AI Institute for Student–AI Teaming. Working on robot learning, cooperative multi-agent RL, and human–AI interaction.

I work primarily on problems at the intersection of robotics and reinforcement learning (RL). Currently, I’m working on multi-agent RL for cooperative control of multi-robot systems. I’m also interested in developing techniques for improving the sample efficiency of model-free RL, especially in the context of robot learning. Before starting the doctoral program at CU Boulder, I worked at a Denver-based startup applying techniques from the latest research in natural language processing to challenges in cybersecurity and legal informatics.

I spent the first two decades of my life in Singapore, but uprooted to the United States for college. In between these two places, I spent half a year living and studying in Russia following an edge-to-edge overland traversal of Europe. But I digress. Drawn to the mountains, I moved to Colorado after my graduation from Reed College. I’ve been here since.

Like almost everyone in Boulder, I enjoy running, hiking, snowboarding, and, well, bouldering.
