Staff profile

I am an Assistant Professor of Computer Science at Durham University, UK. Before this, I worked as a Postdoc in the College of Information and Computer Sciences at University of Massachusetts, Amherst, USA. I received my PhD from the department of Electrical and Computer Engineering at University of Waterloo, Canada, in November 2019. I obtained my Bachelors and Masters degrees in Egineering from Osmania University and Indian Institute of Science, Bangalore, respectively. My research focuses on performance modeling and analysis of communication networks with applications to Cloud computing, Internet of Things, Datacenters, Sensor networks, and Quantum networking. 

Open positions

I am looking for self-motivated PhD students. Please contact me if you are interested in working with me on my current research topics.
