About Me
Hi! I am Weimin Lyu, a 4th year Ph.D. candidate in Computer Science at Stony Brook University, advised by Prof. Chao Chen. I also have the privilege of collaborating with esteemed professors: Haibin Ling, Fusheng Wang, and Tengfei Ma.
Research Interests
My research mainly focuses on Trustworthy AI, especially backdoor attacks/defenses. My goal is to enhance the security of Deep Learning-based models throughout their entire life cycle. The application areas include different tasks across Natural Language Processing and Computer Vision. Experience on explainability in Healthcare and clinical decision making with EHR. Recently I focus on Vision-Language Understanding and Large Language Models.
