Øyvind Weiby Gregersen
About
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 (RISE-PFI).
