ExpertiseRepresentation theory, Topology
ProfileI do research in representation theory of quivers, which can be viewed as advance linear algebra, and its relationship to topology. The main goal of my research is to find connections between different fields of mathematics. I teach advanced graduate courses in Algebra, Topology and I have also taught Mathematical Statistics and Stochastic Processes. Webpage
