I am an Assistant Professor of Electrical and Computer Engineering at UT Austin in the Center for Excellence in Distributed Global Environments (EDGE). I was formerly a graduate student at the MIT Laboratory for Computer Science, where I co-led the MulSaw project. I defended my PhD thesis in December 2003. A PDF version of my dissertation is available here *.pdf.

My research interests include automated software engineering, in particular: static and dynamic checking of code conformance; software testing; repair of structurally complex data; model checking; formal specification languages; parallel and incremental algorithms for software analysis.

My research is funded in part by the National Science Foundation (CAREER award CCF-0845628, and awards CCF-0702680 and IIS-0438967), the Air Force Office of Scientific Research, and the Naval Undersea Warfare Center.
