I am an Assistant Professor in Computer Science at the Chennai Mathematical Institute (CMI), India.

In the recent past, I was a postdoctoral fellow in the Algorithms and Complexity department at the Max Planck Institute for Informatics, Saarbrucken, Germany. Earlier, I was a researcher in the Algorithms group at the Department of Informatics, University of Bergen, Norway.

I obtained my PhD in Computer Science, advised by Prof. Saket Saurabh, from the Institute of Mathematical Sciences (IMSc), India and my masters and undergraduate degree from CMI in Mathematics and Computer Science.
