Steffen has a degree in journalism from Volda University College and a bachelor's degree in Philosophy and History of Ideas from the University of Oslo.

He has extensive experience writing about and communicating research and science: First as a journalist at Forskning.no, Aftenposten and Aftenposten Vitenskap, then as a content producer, project manager and advisor at the marketing agency NewsLab, where he worked with clients such as the University of Oslo, the Norwegian Association for Researchers, the Nobel Peace Center, Microsoft and SINTEF, among others.

Steffen started his career as a journalist working mostly with text, and writing is still closest to his heart. After several years in the marketing industry, however, he has also gained experience in podcast and video production, graphic design and strategic consulting.

At NORSUS, Steffen works to spread all the exciting research coming out of the institute, helps lift LCA as a topic, and supports researchers with communicating their work.
