Research Interests

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).

Selected materials from my tenure packet can be found here.

Prospective students

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.


I will be on leave in academic year 2016-2017.

Previous courses:


  • Computing Over Distributed Sensitive Data Achieve many benefits of data sharing without data owners having to share the data.
  • Privacy Tools for Sharing Research Data Enhance technologies and policies to protect personal data used in research studies.
  • Shill: a secure shell scripting language.
  • Previous projects
    • Accrue Providing language-based security guarantees proportional to programmer effort.
    • CHILI Enabling the execution of code of unknown origin while guaranteeing that the code is not vulnerable to various classes of security attacks.

Brief bio

(Bio suitable for talk announcements, etc.)

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.
