I am a second-year PhD student, studying computer science at UC Santa Cruz, advised by Prof. Chenguang Wang. Previously, I earned a Bachelor of Engineering degree from the TsienHsueshen experimental class at Xidian University and a Master of Engineering degree in Signal and Information Systems from the University of Chinese Academy of Sciences. My CV is available here.

My research interests include: Foundation Models, Agents, LLM Safety.

Works

Software Engineer Internship, Xizhi AI Education. (2022 - 2024)

• Scope: Visually Rich Document Information Extraction.

Xizhi AI Education is a company dedicated to the development of automated problem solving models, famous for developing the Eva Tutor App. I was responsible for extracting certain important information from the user’s questions to use as input for the solution model. After the emergence of LLMs, I was responsible for conducting experiments with prompt design and the local deployment of some small LLMs.
