Teaching: I'm retired, but in the spring of 2026, I am teaching MAT1020
Research: My main research interests are nonstandard analysis and probability theory, especially stochastic processes. Three papers on nonstandard probability theory are Hyperfinite Lévy Processes, Nonlinear Stochastic Integrals for Hyperfinite Lévy Processes, and A Weighted Random Walk Approximation to Fractional Brownian Motion.
Textbooks: I have two textbooks on single- and multivariable calculus in Norwegian, "Kalkulus" and "Flervariabel analyse med lineær algebra" (with Klara Hveberg), and a textbook on intermediate level real analysis in English, “Spaces: An Introduction to Real Analysis”.
Book column: A column (in Norwegian) on mathematics and literature is updated when I have something to write about (and the time to do it!)
