RESEARCH FOCUS
- Research on important general medical questions (e.g. somatization disorder from the physician's and patient's perspective, care situation for patients with thyroid diseases, epidemiological studies on consultation occasions and outcomes, health behavior of medical professionals, teaching research)
- Teaching general medicine, teaching basic medical skills, coordination of different cross-sectional areas, interesting elective subjects. For teaching general medical knowledge, we are supported by practicing specialists as teaching physicians
- Promotion of young doctors i.e. support for medical students who are interested in the subject general medicine and the work of family doctors and
- Continuing education and mentoring of young physicians on their way to becoming a specialist in general medicine

CURRENT RESEARCH
in many nanotechnology applications. Understanding and controlling the influence
of external fields on the shape evolution of nanoscale surface features is therefore of considerable
importance. As a first step in this direction we recently investigated the effects
of an external electric field on the shape evolution of a single-layer islands on a crystalline
surface [1], discovering a remarkable richness of dynamical behavior. We therefore believe,
that the microscopic shape evolution of crystalline surfaces may be controlled through a
macroscopic electric field, which would have large technological impact.
Mathematically this leads to the optimal control of a free boundary problem, where
the free boundaries are given by atomic height steps on the surface (e.g. the edge of a
single layer island) and the external electric field is the control parameter. Our goal is
to investigate this optimal control problem analytically and to provide efficient numerical
methods. Using a phase-field approximation, we will consider existence and uniqueness,
derive the optimality conditions and numerically solve the system of state and adjoint
equations using adaptive finite elements. The extensive use of adaptive mesh refinement
and coarsening – descretizing the state and adjoint variables on independently adapted
meshes – will significantly reduce the computational cost, and these concepts will carry
over to a large class of other optimization problems.
