Harald Oberhauser

Associate Professor at the Mathematical Institute

After finishing his PhD at the Statslab in Cambridge under the supervision of Peter Friz, Harald worked as a postdoc at the Technical University in Berlin. He recently joined the OMI to work as a research fellow within the ERC project of Terry Lyons. His research interests include mathematical finance, SPDEs, rough paths, nonlinear filering as well as computational methods. A unifying theme of these subjects is that they can model the evolution of complex systems that evolve under the influence of randomness. For further information please see here.
