Research

The goal of my research is to make it possible to build secure systems. I seek to identify principles and methods for defining security and for building systems that offer security assurance. I employ mathematical models, programming language theory, and logics. I build real systems and analyze their security. I'm specifically interested in the following areas:

• Security: Electronic voting, security policies, information flow, and cryptography.
• Programming languages: Semantics, logics, and language-based security; specification and verification of programs.

Publications and talks: Complete list of my publications.

Seminars:

• SSL: The GW Systems and Security Seminar [spring 2013][fall 2012][fall 2011]

Software:

• Civitas, a secure electronic voting system.
• PolyJ, improved generics for Java.
• Polyglot, an extensible compiler framework.
