I obtained my BE in 1986 and MTech and PhD from IIT Kanpur in 1988 and 1995 respectively. Between 1988-89, I worked in Indian Space Research Organization, Ahmedabad. I was Member Technical Staff and Team Coordinator in High Performance Computing Group of Center for Development of Advanced Computing (C-DAC), Pune during 1994-97. Since 1997, I am working in the Department of Electrical Engineering of IIT Bombay as a Professor. I was also the Head of Computer Center of IIT Bombay during the period of 2008 to 2011. I am currently Head of Department of Electrical Engineering since January 2012.
My interests span both theoretical as well system design issues. Current research interests are in:
- Control and Performance Modeling of Wireless Networks.
- Quality of Service and Resource Allocation in Wired/Wireless Networks.
- Next Generation Wireless Network Protocols (related to 802.16m, LTE-Advanced and 4G Standards).
- Co-operative Relay and Self Organizing Network.
- Carrier Ethernet and Mobile Backhaul.
- Rural Wireless Network.
Our work in Carrier Ethernet and WiMAX has resulted in contributions to IEEE 802.1 and IEEE 802.16 standards. These contributions can be found here. Though I have mainly looked at networking issues, I am also interested in Digital Communications System theory.
I have supervised several graduate theses. A list can be found here. My current group members are listed here.
I am the Coordinator of Tata Teleservices- IIT Bombay Centre for Excellence in Telecom (TICET). This centre is part of Telecom Centers of Excellence (TCOE) - a public-private initiative established in IITs, IISc Bangalore and IIM Ahemdabad. See here for details. Most of my research is being funded by this centre.
Apart from theoretical research, I am also interested in practical aspects of networking. In IIT Bombay, I have led many technology development projects including open source MPLS router. I also co-founded the venture backed start-up company Eisodus Networks during 2002-2006. The company was engaged in developing technology in the area of Metro Ethernet for India and Asia-Pacific markets. I was also a Technology Advisor to Tejas Networks Ltd and worked closely with their standards and technology team.
Our group is also part of Indo-UK Advanced Technology Center of Excellence in Next Generation Networks, Systems and Services (IU-ATC).
