About

๐Ÿ‘‹๐Ÿป Hi! Iโ€™m an incoming CS PhD student at Stanford University, advised by Prof Fei-Fei Li as part of the Stanford Vision and Learning Lab. Currently, I am also a research intern at NVIDIA Cosmos Lab working with VP Ming-Yu Liu.

Previously, Iโ€™ve spent time at Ai2 PRIOR and Ai2 Robotics. I obtained my BS degree from the University of Washington, where I double majored in computer science (with honors) and statistics, and minored in mathematics. I was privileged to be advised by Prof Ranjay Krishna, Prof Ali Farhadi, Prof Dieter Fox, and Prof Jenq-Neng Hwang. I was also grateful to be mentored by and collaborate with Prof Jiafei Duan and Dr Ying Jin.

My research interests lie broadly in robot learning. In particular, I focus on developing foundation models for robotic manipulation that are deployable in the real world and unlock novel capabilities.
