I am an assistant professor in the department of Computer Science and Engineering, IIT Roorkee. Before joining IIT Roorkee, I was a postdoctoral fellow in the Distributed Algorithms group at Aalto University, hosted by Jukka Suomela and Jara Uitto. I received my PhD in Computer Science and Engineering from Indian Institute of Technology, Kanpur under the guidance of Raghunath Tewari.
I am broadly interested in Algorithms and Complexity Theory.
