Research Interests:

Tectonic Geodesy - 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.
