Background and activities
Johan Sjöblom has been Professor in surface and colloid chemistry and the Head of the Ugelstad Laboratory at the Norwegian University of Science and Technology (NTNU) in Trondheim from January 1st 2002. He was earlier Professor at the University of Bergen during the years from 1988-1999, and Chief Researcher at Statoils R&D Centre in the period 1998-2001. Sjöblom has served as Adjunct Professor of Colloid Chemistry and Materials Science at Clarkson University, Potsdam, New York, and at the Technical University of Helsinki from 1992-1999.
Sjöblom is the editor of 10 books, and the author or coauthor of more than 300 professional papers. He has educated 50 PhD's and 35 MSc's.
Sjöblom is Editor-In-Chief (from 2005) for Journal of Dispersion Science and Technology, and previous Editorial Board Member of Colloids and Surfaces during the period 1993-2003. Sjöblom is also a member of the Advisory Board of Microporous and Mesoporous Materials. He is a member of the American Chemical Society, the Norwegian Chemical Society, and the Finnish Chemical Society. He is also elected Member of the Norwegian Academy of Technological Sciences and the Swedish Academy of Engineering Sciences in Finland. Sjöblom received his PhD degree (1982) in physical chemistry from the Åbo Akademi, Finland.
Sjöblom has been an industrial consultant in colloid chemistry since 1980.
