...my next field experiment will be here...


My main research interests are the earth structure and dynamics.
Often, I exploit the dense station configuration of local seismic networks to obtain results at higher resolution. I try to contribute to a better understanding by using primarily the following methods:
  • Arrival-time & waveform based earthquake location.
  • Analysis of repeating earthquakes.
  • Source parameter studies.

Bachelor & master theses.
If you are interested in doing your bachelor or master thesis in the field of observational seismology: There is generally the possibility to find some seismicity-related topics, e.g. in the frame of our projects in the Northern Chilean subduction zone or the European Alps.
