I am an Assistant Professor in the Computer
Science Department
at Carnegie Mellon University where I lead the CAOS group.
Before, I spent a year at Meta Research.
My research bridges computer architecture and operating systems focusing on performance, security,
and scalability.
My current work follows two central themes: (a) uncovering security vulnerabilities and building
defenses at the boundary between hardware and OS,
and (b) re-designing abstractions and interfaces between the two layers to improve performance and
scalability.
