I am a Ph.D. student in the Department of Computer Science at Purdue University, advised by Prof. Ninghui Li and Prof. Xiangyu Zhang. My research interests focus on security and privacy in machine learning.

Before joining Purdue, I spent a wonderful year as a visiting graduate student at the University of Illinois at Urbana-Champaign, advised by Prof. Tao Xie and Prof. Tianyin Xu. I received an M.S. in Computer Science from the University of Texas at Dallas, advised by Prof. Wei Yang. I was a full-time research assistant advised by Prof. Wei Chen for 1.5 years at Zhejiang University before starting grad school.

Research Opportunities: I am always happy to discuss and brainstorm; if you’re a researcher/student (especially underrepresented minorities) interested in security, privacy, or robust AI (foundation models most recent, e.g., GPT, PaLM, DALL-E), please reach out with subject “[Prospective collaboration]” to zhan4057 at purdue dot edu.
