A Brief History.

I lead the Technology Integration (TechInt) group in the National Center for Computational Sciences (NCCS) at Oak Ridge National Laboratory (ORNL). NCCS hosts the Oak Ridge Leadership Computing Facility (OLCF), which is home to the multi-petaflop Titan supercomputer. TechInt is charged with delivering new technologies into OLCF and other projects at ORNL by identifying gaps in the system software stack and working with the R&D community to develop, harden, and deploy solutions. Our technology scope includes storage systems, data management, high-performance networking, and architecture.

Prior to that, I was a Research Scientist in the Computer Science Research group of the Computer Science and Mathematics Division at ORNL, for over nine years. I joined ORNL in August 2003. In this role, my work had straddled both basic and applied distributed systems research. I have worked on large-scale scientific data management, HPC I/O, storage systems and multicore architectures.

I received a Ph.D. and Masters in Computer Science from the University of Mississippi in 2003 and 1998 respectively. My doctoral work (partly at Argonne National Laboratory, in Chicago, where I was on a Wallace Givens Fellowship and a Dissertation Fellowship) addressed data access issues in the Globus Data Grid environment. In what appears to be my previous life (if you believe in that sort of a thing :)), obtained a bachelors degree in computer science from Karnatak University in India in 1996. I grew up in Madras, South India.
