Until recently he had a part time position as a professor in electric power systems at NTNU in Trondheim, where he worked full time from 2006 to 2013. His research work was mainly within economic optimization of power production including large scale hydro reservoir operation, the use of optimization methods in power system operation and planning, market design and power system balancing. He is the Norwegian member of CIGRE Study Committee C5, and convenor of Working Group C5-27 on Market Design for Short Term Flexibility. He is also member of the board of the Norwegian branch of NAEE.
He has formerly been a member of CIGRE Study Committee 38 and several CIGRE working groups.
Before he became a professor he worked 14 years at SINTEF Energy Research first as a research scientist and later senior research scientist. During this time he also took his PhD titled “Peaking Power in Restructured Power Systems”. In this period he worked on many projects related to economic optimization and simulation of power systems.
