My tasks at the subject group sustainability science comprise both research within environmental engineering and teaching in our undergraduate and master programmes. In my position, I have the management responsibility for a undergraduate programme with engineering focus on technologies and technical systems which aim to mitigate environmental problems through minimized emissions and increased recycling of energy and resource. My research, which is directed towards the development and evaluation of technologies with focus on energy and environmental benefits, also includes supervision of doctoral students in the field of sustainability science.
