Data Analysis Group

The members of the Data Analysis Group perform research and development over a wide range of topics having to do with understanding and making effective use of large-scale data. Our customers include physicists, chemists, mathematicians, and others within the programs at LLNL as well as SciDAC (DOE Office of Science) and the greater computational science community.

Our goal is to enable scientists to concentrate on science by minimizing the effort required to explore and to understand the data generated by their simulations and experiments. This goal drives research efforts in large-scale visualization, data compression and streaming, and sophisticated analysis methods. To learn more about what we do, we invite you to look at some of the projects to which our group members contribute such as LOCAL, and Large-Scale Visualization. Our funding comes from a variety of sources including ASC CSSE, Laboratory Directed Research and Development, and the SciDAC Scientific Data Management Center.
