My research is primarily in operator algebras, specifically C*-algebras. Currently, my specialized interests are in structural properties of C*-algebras, families of representations of C*-algebras, lifting problems, universal C*-algebras, interplay between discrete/ locally compact Hausdorff groups and their universal associated C*-algebras, and algebras associated to groupoids.
