About Me

I’m a PhD candidate in Computer Science at the Louisiana State University (LSU), advised by Dr. Phani Vadrevu. My research interests lie broadly in applied security, with a particular emphasis on web security and privacy. Currently, my work centers on building and deploying scalable systems to measure and analyze various online threats including browser fingerprinting, social engineering attacks, bot-driven fraud, and other abuses, and on designing effective defenses to protect users and services.
