Since 1997, I am working in the Department of Electrical Engineering of IIT Bombay currently as a Professor. Earlier I also worked in Indian Space Research Organization, Ahmedabad (during 1988-89) and High Performance Computing Group of Center for Development of Advanced Computing (C-DAC) (during 1994-97). I was the Head of the Electrical Engineering Department from January 2nd, 2012 to January 4th, 2015. During 2008-11, I also served as the Head of Computer Center of IIT Bombay. I am serving as Dean of Faculty Affairs since February 2017.
Our group is focussed on 5G Wireless Communications specially "Frugal" 5G and Rural Broadband.
I played a leadership role in setting Telecommunications Standards Development Society, India (TSDSI). Read my article in Economic Times on this issue.
The TSDSI was registered in January 2014 and now has more than forty organizations as members in less than a year. Since October 2016, I am the Chairman of TSDSI Governing Council. During 2014-16, I served as Vice Chairman. I am coordinating the overall operations of TSDSI in its formative years. In December 2014, TSDSI was recognized as one of the Organization Partners of 3GPP, a laurel that very few SDOs have achieved in a short span of only one year!
I am also the Coordinating Professor of National Centre for Excellence in Technologies for Internal Security (NCETIS) which is approved by the Department of Electronics and Information Technology (DeitY), Govt of India.
