Research Interests:

Operator algebras, K-theory, wavelets

Research:

I am interested in the broad area of operator algebras, including K-theory and cohomology and their relations to discrete groups and C*-algebraic dynamical systems.  Most recently I have been studying the connection between wavelet and frame theory, operator algebras, and harmonic analysis.
