My main research interest is in classical potential theory, and then in particular questions related to quadrature domains. But I am also somewhat interested in stochastic analysis.

 

Here is a CV.

Earlier versions of some of these articles together with an appendix on classical potential theory are also contained in my thesis.

There is also an errata for the printed version of the thesis (in the version downloadable above these corrections are inserted).
