About
I am a second-year Ph.D. student in the EECS department at the University of California, Irvine, advised by Prof. Athina Markopoulou. I am graduate student researcher in ProperAI.
My research interest is security and privacy issues in AI-powered computing systems. My goal is to identify and mitigate emerging security risks associated with AI technologies, provide a secure environment for users to benefit from AI advancements, and build a reliable platform for developers to exploit AI's potential while maintaining robust security standards.
Before starting my PhD, I worked with Prof. Umar Iqbal, developing a secure platform for LLM-based systems. Prior to that, I spent two years in Prof. Xiaojun Quan's group.
My current research centers on user privacy in AI agents, as well as emerging challenges in agentic commerce. If you're working in these areas, I'd love to connect — feel free to reach out.
