Biography

  • I am a professor in the department of Electrical Engineering at IIT Madras. My undergraduate degree was in Electronics and Communication Engineering from the same department in 1996, followed by a PhD from the University of Maryland at College Park in 2002.
  • I primarily work in the areas of digital system design and VLSI / FPGA implementations of DSP systems, and am part of the Integrated Circuits and Systems Group at IIT Madras.

Research Interests

  • Approximate computing.
  • Low-power signal processing.
  • Architectures for machine learning and techniques for low power/low complexity computation.
