Director of SDSC's Data Enabled Scientific Computing (DESC) divison. DESC is responsible for four major groups: High Performance Computing Systems, User Services, Scientific Computing Applications and Scientific Visualization. SDSC's XSEDE program is coordianted from the DESC divison by Nancy Wilkins-Diehr, Co-PI of the XSEDE program.
Previously I was director 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 NSF funded HPC 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 Medicine and Applied Sciences , UCSD . Our collaborative interdisciplinary research involves
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 received B.S. degree in Electronics and Telecommunication from the Jadavpur University , Calcutta, India, M.S. degree in Nuclear Engineering from Idaho State University 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

al neuroscience research by eleminating the
administrative and technical barrier for accessing HPC resources and thus democratize participation in science by all inclu
ding historically underrepresented groups who find it difficult to access supercomputers. This is a collaborative
