PhD CMU, 1995

My primary research interests are in the development of programming language and compiler technology. I am particularly interested in exploring high-level language facilities for building reliable, secure, and high-performance systems software (e.g. run-time systems, distributed systems). I have concentrated on producing code that is faster and consumes less memory without sacrificing safety or robustness.

My recent work has focused on type systems for extremely low-level languages. Our group has just designed and implemented a type checker for the Intel x86 architecture, and we showed how high-level languages, such as ML, Scheme, Safe-C, and Java, may be compiled to assembly language, yet still be type-checked. This technology provides a means to safely extend systems such as kernels, web browsers, or hand-helds without the overheads of a virtual machine or just-in-time compiler.

I also work with the TILT group at Carnegie-Mellon to produce a type-theoretic compiler for Standard ML and with the Advanced Programming Languages group at Microsoft to explore next-generation implementations of Java.
