Research Interests:

Tectonic Geodesy: I am working as a postdoctoral fellow at GFZ Potsdam. I am interested in the tectonics of fault systems at plate boundaries. Using Global Positioning System (GPS) and Interferometric Satellite Aperture RADAR (InSAR) time-series analysis I model the kinematics in order to understand the driving forces of crustal deformation.

Career:

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, Switzerland

Education:

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

Projects:

  • DFG priority programme "Mountain building processes in 4D (MB-4D)"
  • ALPSHAPE2: Recent kinematics of the Southern and Eastern Alps
  • CaTeNA: Climatic and Tectonic Natural Hazards in Central Asia
  • GeduCA: Central Asian GPS summer school
  • Natural laboratory Central Asia: The tectonic fingerprint of a continental collision
  • Coordination and participation at the GFZ interest group "InSAR Round Table"
