FORSCHUNGSTHEMEN UND -SCHWERPUNKTE
- Forschung zu wichtigen allgemeinmedizinischen Fragestellungen (z. B. Somatisierungsstörungen aus Arzt- und Patientenperspektive, Versorgungsituation bei Schilddrüsenerkrankungen, epidemiologische Studien zu Beratungsanlässen und –ergebnissen, Gesundheitsverhalten medizinischer Berufsgruppen, Lehrforschung),
- Lehre im Fach Allgemeinmedizin, Vermittlung ärztlicher Basisfähigkeiten, Koordination verschiedener Querschnittsbereiche, interessante Wahlpflichtfächer. Bei der Vermittlung allgemeinmedizinischen Wissens unterstützen uns niedergelassene Fachärzte als Lehrärzte,
- Nachwuchsförderung, d. h. Unterstützung Medizinstudierender, die sich für das Fach Allgemeinmedizin und die hausärztliche Tätigkeit interessieren und
- Weiterbildung und Mentoring junger Ärztinnen und Ärzte auf dem Weg zum Facharzt für Allgemeinmedizin

AKTUELLE FORSCHUNG
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.
