Research
My main research focus is on systems and security. I am also broadly interested networking, software engineering, and the legal implications of technology. At Microsoft, I am working with a storage layer for a large cloud computing offering.
UCSD
At UCSD, I was fortunate to have worked with Geoff Voelker, Stefan Savage, and Hovav Shacham.
Return-Oriented Programming
My masters work was with a buffer overflow exploit technique dubbed "return-oriented programming" on the SPARC architecture. I extended the work done in our original CCS paper to automate the search for a Turing-complete set of gadgets. I am performed vulnerability analysis on thousands of Solaris binaries from the Sun Freeware site to make an accurate assessment of the pervasiveness of return-oriented vulnerabilities and investigate the larger implications of the attack in the wild, the results of which are detailed in my M.S. thesis.
Neon
In addition, I have worked with Neon, a virtual machine-based data confinement system using the Xen hypervisor and the Qemu emulator.
