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
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. My current software development is focussed on a branch of WIASHiTNIHS that is designed for shape optimization problems. WIASHiTNIHS is and has been used in the projects Shape Optimization, Crystal Growth in Magnetic Fields (KristMAG, page in German only), and MATHEON C9: Simulation and Optimization of Semiconductor Crystal Growth from the Melt Controlled by Traveling Magnetic Fields.

Mathematical Modeling of Brittle Fracture
Project on the mathematical modeling of crack initiation and propagation in brittle materials using a multiscale approach to local energy functional minimization.

Awards

In 2008, the project Crystal Growth in Magnetic Fields (KristMAG, page in German only) 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.
Reports on this award for the Crystal Growth in Magnetic Fields (KristMAG, page in German only) project can be found here (page in German only), here (page in German only), and here (page in German only).
