I am broadly interested in the study of non-self-adjoint integro-differential operators arising in the investigation of Markov processes and related objects. This encompasses the following topics:
Interwining relations
Spectral theory
Convergence to equilibrium
First passage time problems
Exponential functional of Lévy processes
Subdiffusive processes
The moment problem
Financial and insurance mathematics
