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 student researcher working with the PRIOR team and the Robotics team at the Allen Institute for AI.

Previously, 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, and Prof Jenq-Neng Hwang. I was also grateful to be mentored by and collaborate with Prof Dieter Fox, Dr Jiafei Duan, and Dr Ying Jin.

My research interests lie broadly in robot learning. In particular, I focus on developing generalist robotic manipulation policies that leverage strong priors, by optimizing both the data curation and model architectures.
