Research
I am currently employed in IBM as a Deep Computing (HPC) specialist. I work primarily to analyze and scale applications on IBM's BlueGene line of supercomputers including upcoming BlueGene/Q. Most days I work out of my office in Cambridge, MA. I work with a broad set of computational problems, and enjoy hacking into parallel (MPI, threads, CUDA, mix of all of those) code. Previously I worked with the IBM Future Technology Solution Design Center (FTSDC) in Indianapolis. Prior to this position, I was affiliated with the Novel System Architectures Group in IBM Research Labs, Austin. I worked on implications of multi-core architectures (Cell, GPUs, Intel) on scientific workloads from diverse areas as life sciences, numerical computing and
medical imaging. In graduate school, I worked in the
Laboratory for High-Performance Algorithm Engineering and Computational Molecular Biology specializing in
high-performance computing and computational biology. I worked as a Research Assistant for Dr. David A. Bader on the
IBM PERCS project since Spring 2004, until Fall 2005 when I graduated.
I was recently awarded IBM Outstanding Technical Achievement Award for High-Performance Computing Solutions.
Research Interests
Workload-driven architecture design, Healthcare and life sciences workloads, Performance analysis, Heterogenous architectures, Computational Science, Parallel programming.
Education
I did my Masters in Computer Engineering at University of New Mexico, passing with distinction and earned the Outstanding Graduate Student of Fall 2005 in Computer Engineering. I did my undergraduate education from the Indian Institute of Technology , Guwahati in India.
Personal
I love to play tennis in my spare time, besides other things, I recently won the first ultimate tennis league held in Austin in the 3.5 Mens category.Publications (outdated)
