I am a seismologist within the Earthquake Monitoring and the Earthquake Analysis Sections of the SED. Since September 2015, I am leading the Seismotectonic Group of the SED. My research interests range from basic acquisition of seismological data to tectonic interpretation with focus on observational seismology. Past and present tasks and projects include:

  • Seismotectonic Interpretation
  • High-precision earthquake locations at local to teleseismic distances
  • High-resolution seismic tomography and crustal seismology
  • Earthquake source properties
  • Analysis of earthquakes in Switzerland
  • Lead author of the annual earthquake report of the SED
  • Automatic procedures for detecting and picking of seismic phases
  • Configuration and testing of earthquake monitoring software SeisComp3
  • Receiver Functions
  • Collision, subduction and rift systems
