I am a Lead Member of Technical Staff in the Network Evolution Research
Departmet of AT&T Labs - Research.
My research interests are in the areas of network architecture and design, with special emphasis on restoration.
Prior to joining AT&T, I worked at the routing and signaling group of
Ciena CoreDirector switches and before that at the Networking Research
Department of Lucent Bell Laboratories.
I received my B.Tech. (Computer Science) from Indian Institute of Technology
(I. I. T.), Kanpur,
India and my Ph.D. (Computer Science) from
University of Washington,
Seattle.
