Prabhat is a member of the Scientific Visualization group and the NERSC Analytics team at Lawrence Berkeley National Laboratory. His current research interests include scientific data management, parallel I/O, high performance computing and scientific visualization. He is also interested in applied statistics, machine learning, computer graphics and computer vision. Prabhat received an ScM in Computer Science from Brown University (2001) and a B.Tech in Computer Science and Engineering from IIT-Delhi (1999). He is currently pursuing a PhD in the Earth and Planetary Sciences Department at U.C. Berkeley.
Current projectsI am currently leading the DOE/ASCR funded ExaHDF5 project; which is tasked with scaling HDF5 on current petascale and future exascale platforms.
I was recently funded by the DOE Applied Math program to pursue R&D in scalable statistics and machine learning algorithms for data-centric science. Our project is titled MANTISSA; a webpage is coming soon.
I am also leading the development of pattern detection and spatial statistics tools for the CASCADE SFA.
