About Me

I received my B.S. in Computer Science (along with minors in Math and Physics) from Virginia Tech in May, 2003. I received my Master's in Computer Science from William & Mary in July, 2005 and continued as a Ph.D. Student. In August, 2006 I transferred back to Virginia Tech with my advisor, and I am now a Computer Science Ph.D. Candidate at Virginia Tech.

My research is under the guidance of Dr. Dimitris Nikolopoulos. My interests are high performance computing, systems and programming languages. When I'm lucky, I get to work on projects that lie at the intersection of all three.

Projects

• Cellgen: Implements a subset of OpenMP for Cell. Intended as a research platform so we can investigate programming models and compile/runtime optimziations for the Cell processor.
• Streamflow: A scalable memory allocator for multithreaded applications. Streamflow is designed to avoid synchronization in the common case of local allocation and deallocations. The uncommon case of remote deallocations uses lock-free synchronization. Streamflow is provided as a shared library which replaces malloc() and free() in C and new and delete in C++.
• Factory: An object-oriented library for multithreaded programming in C++. Factory uses existing C++ constructs to express parallelism, without having to rely on language or compiler extensions.
