Research

My research interests are primarily in security including security theory, static analysis, systems security, and security ease-of-use. Recently I've been exploring issues of privacy and privacy enhancing technologies (PETs). In the past, I've done work on operating systems, programming languages, and parallel systems and computation.

Current Research

I'm exploring using TCPA and other such "Trusted Computing" architectures to provide regular folks with enhanced privacy. I'm collaborating with Chris Karlof and Yaping Li for this project.

Papers, Articles, and Past Research

• Object-Oriented Parallel Barnes-Hut was a collaboration with David Garmire in which we implemented the Barnes-Hut N-body algorithm in several different languages, including Titanium and Ruby. Also available in Postscript
• MPI Ruby: Scripting in a Parallel Environment is an article I wrote for IEEE Computers in Science and Engineering. It describes MPI Ruby, an MPI interface to the Ruby scripting language.
• Scalable Unix Commands for Parallel Processors: A High-Performance Implementation describes SUT, a set of tools I wrote while at The Mathematics and Computer Science Division of Argonne National Laboratory. It appeared in some Springer Lecture Notes in Computer Science.
• A Comparison of Static Analysis and Fault Injection Techniques for Developing Robust System Services is a paper I wrote with Pete Broadwell for a CS262B class project.
