Roman Kozlov is a Professor of Mathematics and Applied Mathematics at NHH. He received his Dr. Ing. degree in mathematics from Norwegian University of Science and Technology in 2001.
His research interests include theory and application of differential, difference and stochastic differential equations. He also works on mathematical modelling and numerical methods, which preserve structural properties of the underlying differential equations.
