Background and activities
My work at NTNU
I am dean at the Faculty of Natural Sciences. I was previously vice dean for education and dissemination at the faculty. In addition, I work as a professor in paper technology and paper physics. I primarily focus my research on paper physics, mechanical pulping and production and modification of microfibrillated cellulose. Most of my research is done in close co-operation with the Paper and fibre institute (PFI). Together with a research group at Mid Sweeden University I have started a spin off company called Collimated Chipping Technology, CCT which is working with improoved wood chipping technology.
