I am guest scientist at GFZ and cooperate with several groups and scientists on earthquake observations, surface displacement data and software development.
My main research focus on characterizing earthquake sources. I also study aseismic faulting and volcano-related deformation processes.
My expertise is in space-borne SAR (Synthetic Aperture RADAR) data processing and analysis. In these InSAR data I am primarily looking at crustal deformation signals as caused by larger and/or shallow earthquakes. Using these data of measurable surface displacement I am analysing the properties of the earthquake sources and on the fly I try to improve our techniques methodological. One of my specialities here is the detailed consideration of data errors in the analysis and the error propagation to estimate the model qualities. I also try, where possible, to combine different instrumental data sets to better constrain the models. Where possible I am using as many SAR data as possible, GPS if available, and since recently also seismic data. For the latter, the combination of geodetic and seismic data, I work on methods how to best join these very different data types.
