About Me

I am a senior security researcher at Fingerprint, where I work on web and browser security for bot and fraud detection. Prior to this, I earned my PhD in Computer Science from Louisiana State University (LSU) under the supervision of Dr. Phani Vadrevu, where my research focused on web security, privacy, and large-scale measurement and mitigation of online scams and abuse.
