My research is mainly related to C*-algebras constructed from dynamical systems or combinatorial structures, such as
  • C*-algebras associated with subshifts,
  • graph C*-algebras,
  • C*-algebras of higher rank graphs,
  • groupoid C*-algebras,
  • Cuntz-Pimsner algebras, and
  • C*-algebras associated with product systems of Hilbert bimodules.
I am also interested in algebraic analogous of these kinds of C*-algebras such as
  • Leavitt path algebras,
  • Steinberg algebras, and
  • Cuntz-Pimsner ring,
and their relationship with the corresponding C*-algebras. I also study symbolic dynamical systems in their own right.
