I have received my Ph.D. degree from Xi'an Jiaotong University in June 2025, where I studied under Prof. Chao Shen (沈超). I am fortunate to be advised by Assoc. Prof. Shiqing Ma and Asst. Prof. Juan Zhai during my doctoral studies. I am now a research fellow in Prof. Yang Liu (刘杨)'s team at Nanyang Technological University, Singapore.
My research interests include Software Engineering, LLM Security/Safety, Human-AI Interaction.
👀 Looking for self-motivated undergraduate or graduate students with common research interests to collaborate with.
