My research is mainly focused on tax law interpretation and taxation of closely held companies, but also taxation and social benefits for migrants. I am caurrently leading the project Mutual legal and economic conditions for succesful integration, funded by The Kamprad family fundation.  I have also conducted research in cross border leasing, taxation in the Öresund region (Sweden/Denmark) and tax proceedings in the Nordic countries.

I have acted as supervisor for five doctoral students who all did receive their degree. I am currently supervisor for three doctoral students.

I have been acting as opponent on defends for doctoral degree in Stockholm and Uppsala. I have also been member in graduation committees in Århus, Denmark.
