About Me
I am a research scientist on the AI team at Visa Research, where I focus on the security and privacy of AI systems.
My broader research interests include authentication and authorization, applied cryptography, and distributed systems security. My work often integrates techniques from formal verification, cyber deception, and privacy-enhancing technologies, such as private two-party computation and anonymous communication.
I received my Ph.D. in Computer Science from the University of North Carolina at Chapel Hill in 2021, where I had the privilege of working with Prof. Michael Reiter. After graduation, I continued collaborating with him as a research associate at Duke University. In 2022, I joined Visa Research and spent three rewarding years with talented colleagues on the Security team before transitioning to the AI team in 2025.
