I am a Ph.D. student in Computer Science at the Georgia Institute of Technology's School of Cybersecurity and Privacy where I am advised by Joseph Jaeger. My interests are in applied and theoretical cryptography, and generally in computer security.

I spent the summer of 2025 as a SETS fellow at Cornell Tech where I was hosted by Thomas Ristenpart and the summer of 2026 as a research intern at Microsoft Research where I was hosted by Melissa Chase.

Previously, I was an undergraduate student at NIT Calicut where I was introduced to information security and cryptography by Vinod Pathari.
