Short presentation
I am Professor in Civil Engineering at the Department of Civil and Industrial Engineering at Uppsala University and Head of the Division of Civil Engineering and Built Environment. The research and teaching activities at the division cover the whole span from applied construction engineering to theoretical research on future cities and their energy systems. My own research is focused on city-scale modeling of energy resources and energy performance of the built environment.
