PhD research topic
My work formed part of the
ISLAND PLUME DYNAMIK project of the universities of Frankfurt/M. and Mainz.
Its subject is dynamic modelling of melt generation in the Iceland plume and its application to the interpretation of seismic, gravity and electrical data. For some basic details, see ISLAND PLUME DYNAMIK, project 2; however, the page has not been updated for a long time.
My PhD thesis, Convection and Melting Processes in a Mantle Plume under a Spreading Ridge, with Application to the Iceland Plume (also see the Errata) was defended in May 2004.

Diploma thesis
My diploma thesis (in german, gzipped ps file, about 1.36 MByte) has the title: "Development of a program for
two-dimensional seismic modelling for transversally isotropic media with a
Chebyshev-Fourier method, incorporating the free surface with topography"
(Entwicklung eines Programms zur zweidimensionalen seismischen
Modellierung für transversalisotrope Medien mit einer Tschebyscheff-Fourier-Methode unter Einbeziehung der freien Oberfläche mit Topographie);
it was written in the Applied
Geophysics Group of the Institute of Geophysics in Hamburg. It deals
with a modelling method that basically has been worked out by Dan Kosloff from the Department of Geophysics and Planetary Sciences at Tel Aviv University,
Ekkehart Teßmer from Hamburg University and others and which
uses Fourier resp. Chebyshev operators to calculate the spatial derivatives in
the equations of dynamic elasticity.
You can see two numerical models with short descriptions and small gif movies of some snapshots on a separate page. The first one is an example from my diploma thesis, the second was calculated for this page.

Free stuff
Maybe some stuff I occasionally program is useful for other people, so I am offering it on an extra page.
Photo corner
For photo-lovers, I am continually extending my collection of photos, which I have now moved to my current homepage.
Interesting links
My link list here will not be updated anymore, but remains "frozen"; the current version can be found at my new site. I have split my former link list into several files with respect to the following topics:
Also see the Iceland geophysical link page for some links related to Iceland or to geodynamics in general.
