James Ahrens, Director

Scientist (Applied Computer Science Group)

Dr. James Ahrens of Los Alamos National Laboratory (LANL) is the founder and design lead of ParaView, a widely adopted visualization and data analysis package for large-scale scientific simulation data. ParaView has had an extremely positive impact on the large-scale data analytic capabilities available to simulation scientists around the world. Dr. Ahrens graduated in 1996 with a Ph.D. in computer science from the University of Washington. Following his graduate studies, he joined LANL as a technical staff member. At Los Alamos, he is the leader of an awesome data analysis and visualization team of twenty staff, postdocs and students, as well as a national leader of programmatic initiatives important to the Department of Energy’s (DOE) National Nuclear Security Administration (NNSA) Advanced Simulation and Computing (ASC) program and the Office of Science (SC) Advanced Scientific Computing Research (ASCR) programs.
