My current research is centred on the development of tools and methods for applying artificial intelligence to historical research, focusing mainly on Norwegian, Danish, Dutch, and Spanish sources. 

Most of my published research centres around questions of belief and the connection between belief and action in early modern Europe, specifically in Norway and Spain. The three areas that I have been most focused on have been witchcraft trials, the Spanish Inquisition, and wars of religion. The majority of my scholarly work has been published in English, while my textbooks and books of popular history are in Norwegian.

I have through a number of years worked as Principal Investigator on an extensive database of trials of faith in the Spanish and Portuguese Inquisitions, EMID.
