💾 About Me
I am a first-year Ph.D. student in the College of Information Sciences and Technology at The Pennsylvania State University (PSU), advised by Professor Jinghui Chen.
Before joining Penn State, I received my B.Eng. degree in Artificial Intelligence from Huazhong University of Science and Technology (HUST).
During my undergraduate studies, I was fortunate to work with Professor Huaizu Jiang at Northeastern University and Professor Shan Tan at HUST.
My research interests lie in AI Agent, multimodal large language models (MLLMs), and trustworthy machine learning. I am open for collaborations in research.
I am actively looking for 2026 summer internship opportunities!
