Nygårdsgaten 112, 5008 Bergen, Norway

Per Pettersson has a PhD from the Institute for Computational and Mathematical Engineering, Stanford University, and a PhD in numerical analysis from Uppsala University, Sweden. Both degrees were funded by KAUST (King Abdullah University of Science and Technology).

Pettersson is active in method development, analysis, and implementation of mathematical methods for uncertainty quantification, e.g., polynomial chaos, accelerated Monte Carlo methods, and rare-event simulation. Applications include CO2 storage, CFD, flood modeling, and combustion.

He has been an employee since 2014, first at Uni Research and then NORCE.
