Keerti Choudhary

I am an assistant professor in the Computer Science and Engineering department at IIT Delhi. Prior to that, I was a post-doctoral fellow at Tel Aviv University, and Weizmann Institute of Science. I did my Ph.D. in Computer Science, and Integrated M.Sc. in Mathematics, from IIT Kanpur.

Research: My broad area of interest lies in graph theory and algorithms. Currently, I am interested in Fault-tolerant structures, Extremal graph structures, Dynamic algorithms, Graph-realizability, and Uncertain graphs.

Here is a link to my CV.
