I am a reader in the School of Mathematics at TIFR, Mumbai. Previously I held postdoctoral positions at Temple University, University of Bristol and Technion-IIT. I received PhD from the University of Utah and completed undergraduate studies from IIT Bombay in Engineering Physics. My research is in geometric group theory. I am interested in outer automorphisms of free groups, mapping class groups and CAT(0) groups and cube complexes.

As an undergraduate, I worked with Professor Laurent Bartholdi, at Georg-August University of Gottingen for a summer. Under his guidance I developed some animations explaining what is a torus using POV-ray. Torus movies
In collaboration with Klaus-Peter Brenner and Laurent Bartholdi, I developed computed animated visualization of rotational symmetric structure of the Shona music of Zimbabwe. Webpage
