About Me
I am a research scientist at Visa Research. My research interests are in authentication, applied cryptography, and distributed system security and privacy. My work primarily lies at the intersections of these fields and integrates key elements such as privacy-enhancing technologies, formal verification, and cyber deception.
I received my Ph.D. in Computer Science from UNC at Chapel Hill in 2021, where I was fortunate to be advised by Prof. Mike Reiter. Immediately following my graduation from UNC, I worked as a research associate at Duke University before joining Visa Research in 2022.
