About

I’m a PhD in Computer Science at Northwestern University, advised by Prof. Han Liu. My research focuses on efficiently scaling AI-driven robotics, published at ICRA, ICLR, CVPR, and CoRL. I’ve interned at Meta Reality Lab, Meta’s Ranking & Foundational AI, and Zebra Tech.

I’m broadly interested in robot learning. My research focuses on efficiently scaling AI-driven robotics through computational systems and efficient decision-making. I’m drawn to developing simple, scalable methods that leverage both on-board and distributed compute to accelerate real-world robotic deployment.
