Current Research Projects

Project on shape optimization problems that can be written as optimal control problems subject to (linear or nonlinear elliptic) PDE constraints, where the PDE's domain appears as a variable in the objective functional. Using a fixed domain approach, the unknown domain is encoded via unknown functions of fixed (larger) domain. The objectives include convergence results for numerical approximations as well as the implementation of reliable and efficient simulation software.

Optimal Control and Numerical Analysis of ConductiveRadiative Heat Transfer
Motivated by the goal of computing and optimizing heat transfer at high temperatures in crystal growth apparatus, optimal control and numerical analysis of nonlinear elliptic and parabolic partial differential equations coupled via, generally noncompact, integral operators is the subject of this research project, where the numerical analysis focusses on the finite volume method. In part, this project provides the mathematical foundation for the numerical simulation software WIASHiTNIHS.

WIASHiTNIHS (pronunciation: ~hitnice), the WIASHigh Temperature Numerical Induction Heating Simulator
My current software development is focussed on a branch of WIASHiTNIHS that is designed for shape optimization problems. WIASHiTNIHS constitutes a simulation tool for stationary and transient simulations of heat transport in axisymmetric technical systems that are subject to intense heating by induction. More generally, WIASHiTNIHS allows the numerical solution and control of nonlinear elliptic and parabolic PDE in both axisymmetric and Cartesian settings. WIASHiTNIHS is and has been used in the projects Shape Optimization, Crystal Growth in Magnetic Fields (KristMAG), and MATHEON Project C9: Simulation and Optimization of Semiconductor Crystal Growth from the Melt Controlled by Traveling Magnetic Field.

Awards

In 2008, the project Crystal Growth in Magnetic Fields (KristMAG) received the Berlin/Brandenburg Innovation Award. This project has been conducted with the aid of the software WIASHiTNIHS, which has been created by Olaf Klein and myself. This prize of 10,000 Euros is awarded annually by the German states of Berlin and Brandenburg to a maximum of four applicants for outstanding innovations based on interconnected research. It is particularly aimed at supporting local companies and research groups (see the website of the award agency (in German only) for more information.
A report on this award for the Crystal Growth in Magnetic Fields (KristMAG) project can be found here (page in German only).

Nominated in 2004 by the section Physical Sciences of the Leibniz Association (page in German) for the yearly award for the best doctoral thesis of Leibniz Association researchers (the Leibniz Association has five sections and each section can nominate one candidate). The 2004 award went to the candidate of the section Environmental Research.
Reports on this nomination can be found on Page 24 in the fourth 2004 edition of the journal Leibniz, the quarterly journal of the Leibniz Association (page in German) and in the article Mathematisches Neuland (Mathematics in Uncharted Territory, in German) of the online science news journal scienzz (in German only).
