I am a research assistant professor at Temple University, hosted by Sam Taylor. Previously I was a postdoc at University of Bristol, hosted by Mark Hagen and at the Technion, hosted by Michah Sageev. I received PhD from University of Utah under the supervision of Mladen Bestvina. Before that, I 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 Zimbawe. Webpage
