# Fabian Andsem Harang

Associate Professor - Department of Economics

## Biography

My research is mostly focused around various topics in the field of stochastic analysis, rough path theory, and applications these theories towards financial markets. I am currently very interested in regularization by noise phenomena, especially from a "pathwise" point of view. 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.
