I'm a third-year PhD Student in CSE department at the University of California, San Diego (UCSD).

My research interests lie in the field of computer architecture and security, with a particular focus on microarchitectural side-channel attacks and high-performance defenses such as control flow isolation.

I'm advised by Professor Dean Tullsen, and I am also actively collaborating with Professors Deian Stefan and Kazem Taram.
