Associate professor in life cycle assessment and sustainable production at NTNU Industrial Ecology Programme, and Head of studies in energy and sustainability at NTNU Faculty of Engineering. I teach industrial ecology and sustainable engineering to our undergraduate students, and contribute life cycle thinking and LCA elements to a variety of graduate level courses.


After completing PhD in Industrial Ecology in 2007 I have worked with applied life cycle assessment (LCA) to a wide variety of product systems, including oil/gas extraction, transport and infrastructure, and space technologies. I co-founded and managed an LCA consultancy in Norway, and worked as researcher and lecturer in adjunct positions at NTNU, University of Agder (UiA), and UiT - The Arctic University of Norway. I have been engaged in the establishment and development of innovation clusters within the aquaculture supply industry, and water technologies.

Since 2017 I am employed full time at NTNU, with responsibilities towards study programs, teaching and research activity.

Research Interests

My main interest in the use and development of methods for life cycle-based environmental decision support, lately with increasing emphasis on circular economy and resource efficiency. I specific interest in using these methods to discuss aquaculture, manufacturing and materials production (aluminium, alumina, silicon), household durables, and municipal waste management.
