It is too hard to build trustworthy software systems
using conventional systems APIs. I work on higher-level,
language-based abstractions for programming that better
address important cross-cutting concerns:
Selected recent publications
Effective localization of type errors in the rich type system of Haskell.
An expressive, lightweight genericity mechanism with better
code reuse and stronger static checking
SecVerilog: a security-typed hardware design language for building hardware without
leaks or timing channels
Distributed transactions can be sped up by giving clients time-limited
invariants on state and computation.
Diagnosing maximum-likelihood program error locations from constraint
