Zhiqi (Eli) Wang

I am a second-year Ph.D. student in the College of IST at Penn State University, advised by Professor Yuchen Yang. Previously, I received my Bachelor's degree in Computer Science at RPI, where I was fortunate to be mentored by Lei Yu.

My work sits at the intersection of privacy and security in modern machine learning systems: I study what trained models leak about the data they memorized, and how the inference-time machinery around large language models can fail or be turned against its users.

• LLM Systems Security and Reliability: Characterizing vulnerabilities and failure modes in inference and context-management mechanisms.
• Machine Learning Privacy: Auditing membership privacy and studying its connections to memorization and training dynamics.
