Roger Pearce is now at the Center for Applied Scientific Computing at Lawrence Livermore National Laboratory since August 2013. Please visit his new web page.

Roger Pearce obtained a Ph.D. in Computer Science from the Department of Computer Science and Engineering at Texas A&M University working with Prof. Nancy Amato in the Parasol Lab. In 2008, he joined Lawrence Livermore National Laboratory as a Lawrence Scholar working with Dr. Maya Gokhale . He received a B.S. in Computer Engineering from Texas A&M in 2004. His research interests center around parallel and external memory graph algorithms and data-intensive computing. Before joining LLNL, Roger worked on sampling based motion planning algorithms for robotics applications. His research was also supported in part by a DOE GAANN Fellowship (2006-2007).
