at UiO in 1992 with the thesis “Mathematical models of lake ecosystems.” Seip has served at several positions at Center for industrial research, SI / SINTEF.
From 2011 he has been professor and vice dean for research and development at the Faculty of technology, arts and design at Oslo and Akershus University College of applied Sciences.
Seip has worked in applied mathematics with problems related to doubly curved surfaces, within the ecological field with models of rocky shore and lake ecosystems (e.g.,;[1][2]), with oil pollution,[3] and with population cycles in terrestrial environments.
The first extends the analysis of associations with analyses of “leading” and “lagging” relationships for cyclic phenomena.
Both methods are used to characterize the behavior of actors, for example as competitors, facilitators and gainers or engineers.
