I am the Robert Sansom Professor of Computer Science at the Department of Computer Science and Technology in the University of Cambridge. I received a B.Tech in Computer Science and Engineering from IIT Delhi in 1986 and a Ph.D. in Computer Science from the University of California, Berkeley in 1991. I was subsequently an MTS at AT&T Bell Labs and an Associate Professor at Cornell. In 1999 I left academia to co-found Ensim Corporation and GreenBorder Technologies Inc. Returning to academia, I was at the University of Waterloo from 2003 to 2019 holding first a Canada Research Chair and then the Cisco Chair in Smart Grid. My honours include being named Fellow of the Royal Society of Canada, ACM, and IEEE, a Distinguished Alumnus of IIT Delhi, two Test of Time awards from ACM SIGCOMM, and Best Paper awards at ACM SIGCOMM, MOBICOM, and eEnergy. I am the author of two graduate textbooks on computer networking and have served as Chair of ACM SIGCOMM.
