In the field of history, my research interests have focused
geographically on European history, especially the Baltic and the North Seas
Region, the Nordic countries, Germany and the Netherlands. Regarding historical
periods and themes, I have specialized in Early Modern period, history of
international relations and diplomacy, maritime history and development of
modern states system. Concerning Finnish history, it is also worth mentioning
that I have familiarized with the
history of Scout movement in Southwest Finland.

In my ongoing Doctoral dissertation project I am focusing on the
control of the Danish Straits and especially the Sound (in swedish Öresund)
region in the history of international relations in the Baltic and the North
Seas region during the 17th century. I approach the subject by examining the
role of dutch-born entrepreneur Louis De Geer in the maritime conflict
concerning the control of the Sound and his agency during the war between
Sweden and Denmark 1643-1645.
