Research Interests:
My main research interests are operator algebras and functional equations.
On operator algebras, I am currently interested in higher rank graph algebras. They are natural operator algebras associated with higher rank graphs, which are higher dimensional analogues of directed graphs. They have been attracting a great deal of attention recently. On one hand, there are some results generalized from graph algebras; on the other hand, they are significantly more complicated than graph algebras, and provide more intriguing operator algebras.
On functional equations, I am interested in studying them by applying harmonic analysis and representation theory. This gives close connections between functional equations and other areas.
Editorial Board: I am an editor for Banach Journal of Mathematical Analysis (2014  )
