About me

I joined the VUSec group in 2019 as a PhD student. My research interests span systems security, program analysis, and microarchitectural attacks.

Previously, I did my MS at UC San Diego, where I worked with the security group. Before that I did my BS at the University of Arizona, where I worked on the Lynx Project.
