Research Interests:
Since a number of years I am mainly studying the global upper mantle structure with the S-receiver function technique, which I am constantly trying to improve. In my opinion this technique is the most useful method to image seismic discontinuities in the upper mantle. There are plenty of open broadband data available which are underused and which can easily be used for that purpose. I think, before we can really understand continental collision in various parts of the Earth we need much better images of the structures within the upper mantle. The increase of our knowledge is directly proportional to the number of installed and used high quality seismic stations.
