About me

I’m a second-year PhD Student in the Computer Science and Engineering department at the University of California, San Diego (UCSD). My research interests lie in the field of computer architecture and microarchitecture 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 Professor Deian Stefan.
