Ole-Morten Midtgård

Professor

Electric Power Engineering

I started as professor in Electric Power Engineering at the University of Agder in 2004. I was strongly involved in building up our study programmes in Renewable Energy, and I have lectured on all levels in this field, as well as in the Master's programme in Mechatronics. I was also a key person in building up the university's research in End Use of Photovoltaic Technology, through leading a project supported by the Research Council of Norway and Elkem. Since 2012 I have had my main position at the Department of Electric Power Engineering at NTNU in Trondheim, where I am presently the Head of Department. But I still have an affiliation with the University of Agder.
