My research helps programmers write trustworthy programs. My primary area of interest is language-based information security: using programming language techniques to provide information security assurance. You can find out more about my research in this research statement (from August 2015).

I currently have an opening for a postdoctoral fellowship. Also, information for prospective students, both undergraduate and graduate, can be found here. Please read this page before contacting me. General information for Harvard undergraduates interested in research in Computer Science is available here.
My research is currently supported by the National Science Foundation (under Awards 1054172, 1237235, 1421770, 1524052), the AFOSR, an Alfred P. Sloan Research Fellowship, and a Google Faculty Research Award. I have previously been supported by IARPA.
I completed a Ph.D. at Cornell University in August 2008, under the guidance of Andrew Myers. Prior to graduate school, I spent several years working as a consultant and contractor. I received a B.Sc.(Hons) and B.A. from Victoria University of Wellington, in Wellington, New Zealand. My wife, Kiran Gajwani, is a Lecturer/Advisor in the Economics Department at Harvard.
