I am a final-year Ph.D. candidate in Electrical Engineering and Computer Science (EECS) at the University of Kansas, advised by Prof. Fengjun Li and Prof. Bo Luo. I expect to graduate in December 2026 and am actively seeking full-time opportunities beginning in 2027. My research focuses on the security and privacy of machine learning systems, including model protection, deepfake defense, and image copyright protection. I am also broadly interested in machine learning systems and applications, particularly recommender systems and large language models.
