I joined the
Teletraffic Theory and Performance Analysis department in
AT&T Bell Labs as Member, Technical Staff, after my PhD (in 1994), which later became the
Network Design and Performance Analysis
department of AT&T Labs. I was member of a core Labs team responsible for performance analyses, system bottleneck identification and
improvement, performance measurement, modeling and capacity
planning of various services and products at AT&T. During my time at AT&T I worked on diverse technologies
ranging from telephony switches, multi-tier Web applications to wireless services.
I moved back to India and joined the faculty in this department in 2002. During the academic years 2009-2011 I was on leave in
Bangalore as Visiting Faculty at the
Computer Science and Automation Department,
Indian Institute of Science, Bangalore. While in Bangalore, I also worked at IBM Research Labs
as part-time Visiting Researcher from June 2009-May 2010.
