About Me
    Finding simple solutions to complex/challenging problems motivates me. Apart from being a PhD student at IITH, I also have spent several years in the software industry.
      Education

  • B.E. (Electronics & Communication Engg.),   UVCE, Bangalore

  • M.S. (By research),  IIIT, Bangalore

      Research
    I am broadly interested in large-scale processing systems, high performance computing, storage systems, file systems and databases. As part of my PhD research, I am developing efficient and cost-effective techniques for the Approximate Nearest Neighbour (ANN) problem using GPUs. My Ph.D. advisor is Dr. Jyothi Vedurada
