I am a Ph.D. student in Computer Science at Indiana University Bloomington, advised by Prof. Hanqing Guo in the ASPIRE Lab. Before joining IU, I was a Ph.D. student in Electrical and Computer Engineering at the University of Hawaiʻi at Mānoa, also with Prof. Guo.

My research focuses on AI security, particularly AI agents’ RAG systems, and data governance. I investigate adversarial attacks and practical defenses for secure AI systems, as well as audio watermarking. I spent 5 years in industry as a data scientist and product manager, working on semiconductor yield analytics and forecasting systems.
