It is too hard to build trustworthy software systems. I aim for
simple, high-level abstractions that offer programmers strong
guarantees about cross-cutting concerns:
Selected recent publications
An abstract yet expressive model for reasoning robustly about the
interaction between authorization and information flow.
Effective localization of type errors in the rich type system of Haskell.
(Distinguished paper award)
An expressive, lightweight genericity mechanism with better
code reuse and stronger static checking
LALR parsers can illustrate parsing conflicts with counterexamples
SecVerilog: a security-typed hardware design language for building hardware without
leaks or timing channels
Fabric: A federated system for securely storing, sharing, and computing information.
- SHErrLoc: The Static Holistic Error Locator
identifies the most likely locations of program errors by analyzing the program constraint graph.
- Controlling timing channels by static analysis and dynamic mitigation
- Jif: an extended
version of Java that protects privacy by controlling information flow.
Civitas: A practical, secure, remote voting system.
- JMatch: a
Java extension with pattern matching and interruptible iterators
a widely used, extensible Java compiler front end framework for rapid
experimentation with new language extensions.
