Ranjita Bhagwan




I am a researcher at the Mobility, Networks and Systems group at Microsoft Research, India. My interests are mainly in solving problems related to Networking and Distributed Systems.



Brief Bio


I completed my PhD on availability in large-scale distributed storage systems in 2004 from the University of California at San Diego. I worked for two years at the IBM T. J. Watson Research Center on designing and developing a large-scale stream processing system. In the beginning of 2007, I joined Microsoft Research India in Bangalore.
