Øyvind Weiby Gregersen

Øyvind Weiby Gregersen is a Professor at the Department of Chemical Engineering, Norwegian University of Science and Technology (NTNU), and former Dean of the Faculty of Natural Sciences. His work spans paper physics, mechanical pulping, and microfibrillated cellulose research, with close collaboration at the Paper and Fibre Research Institute (RISE-PFI).

• Academic focus areas: Paper physics, mechanical pulping, nanocellulose, CO2 separation
• Key institutions: NTNU, RISE-PFI
• Leadership roles: Dean (Faculty of Natural Sciences), Vice Dean (Education and Dissemination)

His research centers on cellulose-based nanocomposite membranes, particularly for gas separation applications like biogas upgrading and CO2 capture. Collaborative projects with RISE-PFI emphasize sustainable materials for packaging and energy systems.

Recent publications highlight trends in TEMPO-oxidized nanocellulose, phosphorylated fibrils, and PVA composite membranes for gas separation. His work also includes fundamental studies on nanocellulose properties and industrial applications in paper production.
