Kort presentation
Jag är professor vid Institutionen för samhällsbyggnad och industriell teknik vid Uppsala universitet och föreståndare för Avdelningen för byggteknik och byggd miljö. Forskningen och undervisningen vid avdelningen omfattar ett brett område, från byggteknik till framtida städer och deras energisystem. Min egen forskning är inriktad på modellering och simulering av energiresurser och energisystem i den byggda miljön.
