Brief Biography

My research interests are in programming languages, verification, compilers, tools, and applications. I currently focus on high-assurance systems software development, especially formal verification of runtime system components, as part of the HASP project at PSU and the SOUND project, which is joint with BAE Systems and UPenn. My past publications, mostly about functional languages, include work on debugger implementation, garbage collection, compilation, integration with logic languages, and lazy functional algorithms. I teach courses in programming languages, compilers, semantics, and theorem proving.
