About

I am a fifth year CS Ph.D. candidate at The University of North Carolina, Chapel Hill advised by Prof. Mohit Bansal. My research focuses on multimodal AI and agentic systems for understanding and reasoning across different modalities (especially videos). My goal is to develop effective and efficient systems that integrate perception and reasoning to solve complex real-world problems. I am a recipient of the Bloomberg Data Science Ph.D. Fellowship.

I am on the job market, looking for full-time Research Scientist positions starting Summer 2027. Feel free to reach out!

Research Interests

I build multimodal systems that perceive and reason over long and complex videos. My recent work follows three directions:

• Agentic video understanding
  VideoTree (CVPR 2025) · Active Video Perception (CVPR 2026) · Searching Videos as Trees (NeurIPS 2026)
• Efficient video reasoning with LLMs
  Video-RTS (EMNLP 2025) · LLoVi (EMNLP 2024) · SiLVR (TMLR 2026) · MEXA (EMNLP 2025)
• Long-horizon memory and verifiable reasoning
  EgoMemReason (COLM 2026) · Multimodal Fact-Level Attribution (ICML 2026) · Evidence-Backed VideoQA (ECCV 2026)
