USEFUL[?] TOOLS

A simple RPC library based on Google Protocol Buffers.

xv6p is an extension to the xv6 operating system that adds support for paging; this simple paging implementation was used as a pedagogical tool for an operating systems course.

Though it is based on the work of many researchers at the Paradyn project, I was largely responsible for the ParseAPI binary code parsing library.

DISSERTATION RESEARCH

Computer program binaries are the end result of a process that starts with an idea in a programmer's mind and culminates with an executable program. Along the way, the nascent program undergoes a variety of transformations: instantiation in a programming language, compilation by particular compiler with specific compilation options, and possible post-compilation transformation like link-time optimization or obfuscation or packing. We refer to the specific stages of this transformative process---from the program author down---as the program's provenance. The central hypothesis of our research is that evidence of this process remains encoded in program binaries, and can be recovered to give insight into how binaries were produced, with applications in software engineering and debugging, malware analysis, and digital forensics.

My dissertation, Six Years in Provenance, is available.

OTHER INTERESTS

Aside from my doctoral research, I am interested in virtualization, particularly from a security context, and in operating and distributed systems in general. I also enjoy playing around in OS code, which tendency has been occasionally exploited.
