About Sandy
I am a second-year M.S. student in Computer Science at University of California, Davis, advised by Dr. Lifu Huang. My research focuses on agentic AI, multimodal reasoning, and trustworthy LLMs.
Previously, I earned my B.Eng. in Information Security at Hefei University of Technology in 2025, advised by Dr. Yuanzhi Yao.
Selected Research Projects
Open-Ended Video Game Glitch Detection with Agentic Reasoning and Temporal Grounding
TL;DR An agentic framework that detects glitches in gameplay videos, explains what went wrong, and pinpoints when it happened.
Benchmarking Long-Horizon Video Understanding
TL;DR A comprehensive benchmark evaluating how multimodal models track entities, reconstruct evolving states, and integrate evidence across long videos.

Miscellaneous
In case you are more interested in me than my research……
I am deeply obssessed with mystery and (especially linguistic) puzzle games. Here is part of my steam library: Rusty Lake, Return of the Obra Dinn, Slay the Princess, Chants of Sennaar, The Message from Deep Space, Word Game, and Baba Is You.
I guess this is the end. Thank you for reading this far :)
