About Me

I am a CS PhD student at UT Austin advised by Calvin Lin and Shravan Narayan working on building defenses for micro-architecture side-channel attacks.

Previously, I worked in the Purdue University Programming Languages Group (PurPL) advised by Professor Milind Kulkarni where I worked on path explosion for symbolic execution engines and accelerating irregular algorithms with ray-tracing hardware.
