I am interested in all aspects of geomagnetic induction in the Earth and particularly, to increase the acceptance of the magnetotelluric method (MT) in the wider Earth Science community. Over the last couple of years, I have been involved in a series of large scale MT projects to investigate active and fossil tectonic regimes in all parts of the world. Almost all of these projects have been embedded in a multi-disciplinary framework and our electrical conductivity studies have become a valued and important aspect in an integrative interpretation of all acquired geological and geophysical data.

I am also responsible for developing the MT component of the geophysical instrument pool of the GFZ. High resolution electrical conductivity models which are meaningful for other geoscience disciplines require modern experimental designs with data being recorded with dense site spacing and over a broad frequency range. The MT instrument pool has been the backbone for our successful experimental work and its size and quality is probably unrivalled in the world.

Another aspect of my research includes teaching at the Free University of Berlin and organizing (together with H. Brasse) the Berlin/Brandenburg seminar on electromagnetic induction. This seminar is open to students and researchers from all nearby Universities (FU Berlin, TU Berlin, U. Potsdam) and the GFZ. I am convinced that MT has a great future and therefore, I will continue to open possibilities for interested students to work with us in international projects and to use data for academic theses.
