Last updated: 19 September 2026
I am a second-year Ph.D. student in Computer Science at Dartmouth College. I am a member of the SAHAS Lab, where I am honored to be advised by Prof. Nikhil Singh and work at the intersection of AI Agents and Computer Vision.
I worked as a research intern at Alibaba DAMO Academy, mentored by Dr. Tian Zhou. I also served as a Visiting Student with Prof. Ming-Hsuan Yang at UC Merced and Google DeepMind and Prof. Chao Ma at Shanghai Jiao Tong University. I have previously collaborated with Prof. Lu Qi and Dr. Xiangtai Li at TikTok, as well as with Prof. Junwei Liang at AI Thrust, HKUST(GZ).
My Ph.D. research builds visual intelligence for AI agents.
My research interests span:
- (1) Visual memory for agents
- (2) Agentic reinforcement learning
- (3) Long-horizon reasoning and decision-making
