I am a PhD student at Unviersity of Maryland, College Park. I am advised by Prof. Dinesh Manocha in GAMMA group. I received my B.S. in Computer Science and Statistics at UMD in 2019 with Magna Cum Laude.

My primary goal is to equip autonomous agents with general and versatile capabilities. To tackle this challenge and connect the dots, I work on the topic of large vision-language model, foundation model for robots, robotic applications, autonomous driving and computer vision. Previously, I did research internships at Amazon Lab126 and Baidu USA. My CV can be found here.
