My interests lie broadly at the synergistic intersection of computer architecture, systems software and middleware, and applications software. Most recently, my research has dealt with high-performance networking protocols, dynamic multicore scheduling, accelerator-based computing for bioinformatics, virtual computing, power-aware computing, and bioinformatics in general. I joined Virginia Tech in 2006 after spending seven years at Los Alamos National Laboratory, operated by the University of California. I am the recipient of three Best Paper Awards in human-computer interaction, high-performance networking, and bioinformatics, respectively, and three R&D 100 Awards in green supercomputing, high-speed networking, and bioinformatics, respectively. I lead the Synergy Laboratory as well as three grassroots projects:

The Green500 List: A ranking of the most energy-efficient supercomputers in the world.

mpiBLAST: An open-source, parallel implementation of NCBI BLAST.

Supercomputing in Small Spaces: Green supercomputing, i.e., low-power and power-aware supercomputing
