I work in operator algebras. My topics of interest are C*-dynamical systems, locally compact groupoids and bivariant K-theory.

This page contains (i) list of my publications and preprints along with links to arXiv articles, (ii) mathematical notes I wrote for various purposes, (ii) a link to my popular math or math related publications and preprints.
