Academic Interests

Besides my work in mathematical modelling and applied statistics, I have been interested in innovation and entrepreneurship in the university sector. This started during a sabbatical leave at Stanford University in 1997 - 98, where I saw how a high emphasis on innovation was combined with excellent research. After returning home, this experience gave rise to the Norwegian School of Entrepreneurship which is now run by the Centre for Entrepreneurship at the University of Oslo - http://www.mn.uio.no/sfe/. In the ensuing years, I have worked with innovation and entrepreneurship in different settings.

Today, we have a Norwegian economy in increasing need of renewal and the universities are expected to play a considerable role in the necessary restructuring. The universities must respond by increasing their efforts within innovation but at the same time realize and create an acceptance for the fact that this will require changes both in the internal culture and mindset, all taking time. Furthermore, such changes cannot involve all disciplines at a university as broad as the University of Oslo. It is a challenge to develope and implement suitable instruments in mutual understanding with the various disciplines and external actors.
