Spectral and scattering theory for the Schrödinger operator
Current research

I am interested in how the geometry of space influences solutions to PDEs. I am studying spectral and scattering theory for the Schröodinger operators on non-compact manifolds and infinite graphs. It is interesting that a method invented to overcome a geometric difficulty has found applications to some problems in the Euclidean space.
