# Fabian Andsem Harang

Førsteamanuensis - Institutt for samfunnsøkonomi

## Biografi

My research is mostly focused around various topics in the field of stochastic analysis, rough path theory, and applications these theories towards economic modelling and financial markets. I am currently very interested in mean field equations and mean field games, and applications in modelling of economic growth. I am also actively working on projects related to Volterra rough paths, rough volatiltiy modelling, and generally the application of stochastic processes with memory in finance.
