Profile
I am a post-doctoral research staff member at the Lawrence Livermore National Laboratory. I was a post-doctoral research associate with Profs. Laxmikant V. Kale and William D. Gropp uptil June 2011. Please find more about my current interests and list of publications below.
I received my Bachelor of Technology degree in Computer Science and Engineering from Indian Institute of Technology Kanpur in 2005. I received my Master of Science and Doctor of Philosophy degrees in Computer Science from the University of Illinois in 2007 and 2010 respectively.
