Research Interests:

Tectonic Geodesy: I am a postdoctoral fellow at GFZ Potsdam. I am interested in the tectonics of fault systems at plate boundaries. Based on Global Navigation Satellite System (GNSS) and Interferometric Satellite Aperture RADAR (InSAR) time-series analyses I model the source kinematics in order to understand the driving forces of crustal deformation.

Career:

Since 2013  Post-Doc, Lithosphere Dynamics, GFZ Potsdam, Germany
2015 / 2018 Parental leave
2008 - 2012 Research assistant, Institute of Geophysics, ETH Zürich, Switzerland
2007 - 2008 Spectraseis Technologie AG, Zürich, Switzerland
2005 - 2006 Swiss Seismological Service, Zürich, Switzerland

Education:

2008 - 2012 PhD, Institute of Geophysics, ETH Zürich, Switzerland 
2000 - 2005 Diploma, Interdisciplinary Natural Sciences, ETH Zürich, Switzerland 

Projects:

Teaching:

  • Geophysical Field Course - hammer stroke seismics, ETH Zurich (BSc)
  • Crustal deformation measured with radar satellite interferometry (InSAR), Theory and Practicals using a case study, Potsdam University (MSc 4ECTS)
  • Supervision of 1 PhD, 2 MSc, 1 BSc theses and 1 intern
