I am an Institute Postdoc at ICERM, Brown University.
I completed my PhD in Mathematics at Georgia Tech, under the direction of John Etnyre.
I received my undergraduate and masters degrees from Chennai Mathematical Institute.

Research Interests

I am primarily interested in Geometric Topology, in particular embeddings, knottings and braidings of manifolds.
I also study Contact and Symplectic Geometry and Combinatorial/Geometric Group Theory.
