Harald Johan Walderhaug is a Professor of Environmental Sciences at the University of Oslo, affiliated with the Department of Chemistry under the Faculty of Mathematics and Natural Sciences. He holds a Ph.D. in Physical Chemistry from Lund University (1985) and has been a permanent faculty member since 1995. His research focuses on molecular dynamics and transport in organized fluid systems, with particular emphasis on NMR methods applied to polymers, colloids, gels, and microemulsions. He teaches courses such as KJM1130 (Physical Chemistry I), KJM5500 (Surface and Nanochemistry), and KJM-Mena3300 (Physical Chemistry III). His work spans over three decades, with publications analyzing polymer diffusion, surfactant behavior, and complex liquid structures using advanced NMR techniques. Notably, he has contributed to studies on block copolymer micelles, microemulsion systems, and polyurethane formulations for rocket propellants. Walderhaug serves as Secretary General of the Norwegian Chemical Society and has been a key contributor to understanding colloidal systems and molecular transport mechanisms. His research often bridges physical chemistry with applications in materials science and environmental chemistry.
