+91-44 -2257- 4728/5695


  • Dr. Sujatha graduated with her B.Tech in Mechanical Engineering from IIT-Madras in 1992, her MSME from the University of Toledo, USA in 1994, and after a long stint in the prosthetics industry, her PhD from the Ohio State University in 2007. She joined the faculty at IIT-Madras in 2008.
  • Dr. Sujatha’s work is in the areas of Prosthetics and Orthotics, Biomechanics and Mechanisms. She heads the TTK Center for Rehabilitation Research and Device Development (R2D2), which focuses on the development of assistive and rehabilitation devices that are biomechanically and economically suited to Indian lifestyles and conditions. R2D2 works towards commercializing the devices with industry partners or startups, having accomplished it successfully with the Arise Standing Wheelchair and NeoFly-NeoBolt: devices for seamless indoor-outdoor wheelchair mobility.
  • Dr. Sujatha’s team members have won awards at prestigious competitions for their projects and have several Indian and international patents granted/pending for assistive device designs. She is also co-inventor on several US and international patents for prosthetic designs from her prior work.

  1. R2D2 has been awarded the ‘Best Assistive Technology Initiative Among Educational Institutes’ by Assistech Foundation (ATF) – 2021
  2. Prof. Sujatha Srinivasan has been conferred the Abdul Kalam Technology Innovation National Fellowship for a period of 3 years starting Feb 01, 2020
