### Research Focus

Representation theory, noncommutative geometry

My research interests include representation theory, algebraic geometry, homological algebra, and mathematical physics. I am particularly interested in various interactions between these fields. Some of my recent work is related to derived algebraic geometry, algebraic homotopy theory and their applications in representation theory and low-dimensional topology.
