About Research The Stochastic Processes and Mathematical Statistics group, led by Prof. David Bolin, develops methodology for statistical models involving stochastic processes and random fields. A main focus is the development of statistical methods based on stochastic partial differential equations. This exciting line of research combines methods from statistics and applied mathematics in order to construct flexible and physically interpretable statistical models, and efficient computational methods for statistical inference. Current areas of focus include the following: Random fields on metric graphs Many

Stochastic Processes and Mathematical Statistics Front Page Led by Prof. David Bolin, the Stochastic Processes and Mathematical Statistics research group develops methodology for statistical models involving stochastic processes and random fields. A main focus is the development of statistical methods based on stochastic partial differential equations (SPDEs), and current main areas of research are random fields on metric graphs and networks, stochastic processes formulated through fractional-order SPDEs, and non-Gaussian random fields. More details on our work can be found in the About section, and details on the software we develop can be found in
