I am group leader of the Scientific Computing Applications group at the San Diego Supercomputer Center. The computational scientists, in the group, have expertise and experience in High Performance Computing (HPC) and have degrees in various domain sciences such as mechanical engineering, hydrology, biochemistry, nuclear engineering, and physics. The group's main activities are HPC research and development work in collaboration with domain science users of TeraGrid resources. This collaborative R&D effort allows SDSC's experienced computational scientists to work with domain scientists regarding algorithm development, code optimization, code profiling/tuning, mathematical library implementation, new programming model implementation etc.

I am an Associate Professor in the Department of Radiation Oncolgy, UCSD. Our collaborative interdisciplinary research involves application of HPC for adaptive radiation therapy. We are specifically exploring use of GPUs for real-time re-planning where we need to solve three computationally intensive tasks: patient modeling based on deformable image registration, radiation transport simulation and dose calculation using Monte Carlo methods, and treatment optimization as a large scale optimization problem.

I am the Area Director for Advanced User Support for TeraGrid which is an open scientific discovery infrastructure combining leadership class resources at eleven partner sites to create an integrated, persistent computational resource.

I received B.S. degree in Electronics and Telecommunication from the Jadavpur University , Calcutta, India, and Ph.D degree in the interdisciplinary program of Nuclear Engineering and Scientific Computing from the University of Michigan . My dissertation was done under the supervison of Prof. William R. Martin. Before joining the SDSC I worked for a year at the Engineering and Computer Center at the Ford Research Laboratory in Dearborn, Michigan.

Current Projects:
