INTEREST AREAS

Dr. Lorentz has a wide range of interests ranging around numerical analysis. It includes approximation theory, multivariate interpolation, wavelets, the numerical solution of PDE's with the multigrid method and radial basis functions, all of these both from the applied as well as the theoretical point of view.Currently he is concentrating on applying mathematical methods to the compression of data resulting from numerical simulations, such as automotive crash simulation, CFD and weather forecasting. He was involved in the production of software - FEMZip - now used by many automotive manufacturers (Daimler, Porsche,GM etc.) as well as software - GRIBZip - used by the German Weather Service. For this work, a group of three researchers including him were awarded the prestigious Joseph-von-Fraunhofer-Prize for Technological Innovation in the Computer Sciences, 2007. In addition, he has submitted a patent application concerning the algorithm used in GRIBZip and is preparing another patent application concerning the algorithms used in new CFD compression software.
