Research Topics, Overview of the research

• Research Topics

  Operator algebra theory

• Overview of the research

  My research interests are in functional analysis in general, and more specifically in operator algebras. I have been working on constructions of C*-algebras from noncommutative dynamics and their generalizations. I am interested in understanding how structural properties of these operator algebras interact with the underlying dynamics and combinatorial data. I am also interested in the interplay between non-selfadjoint and selfadjoint operator algebras.
