Curriculum VitaeLinkedIn profile example
I work with the Computational Science Division of IBM in Cambridge Massachusetts. Prior to this position, I was affiliated with the Novel System Architectures Group in IBM Research Labs, Austin. I work on implications of multi-core architectures (Cell, GPUs, Intel) on scientific workloads from diverse areas as life sciences, numerical computing and medical imaging. Previously, 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 am continuing my focus on life sciences and healthcare workloads, and high-performance computing inside IBM. Recently, I have worked on Cell implementations of popular bioinformatics applications like Smith-Waterman, Clustalw and HMMER (see Publications below). I am working on an implementation of Jaccard coefficient on Cell, GPUs and Intel processors, comparing performance, and programmer productivity for each of these platforms. I also maintain and update BioPerf bioinformatics benchmark suite with my advisor Dr. David A. Bader
Workload-driven architecture design, Healthcare and life sciences workloads, Performance analysis, Heterogenous architectures, Computational Science, Parallel programming.
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.
PersonalI 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.
