Funktion und Aufgaben:

PhD Student with Prof. Niels Hovius (Section 4.6 Geomorphology) and Dr. Jens Turowski (Section 4.6 Geomorphology).

Wissenschaftliche Interessen:

I am generally interested in environmental seismology, for example how seismic signal can be used to obtain information on river activity (water turbulence, bedload flux, ect.) or on landslide dynamics and initiation mechanisms. My lines of research are currently:

  • Machine learning techniques to retrieve information from landslide seismic signal
  • Seismic Interferometry and Ambient Noise Seismology
  • Crack propagation modelisation
  • Crack propagation physical mechanisms

Karriere:

Since September 2019:PhD Researcher at the Deutches GeoForschungsZentrum, Potsdam.

Projekte:

My PhD project at the GFZ aims to better understand and monitor crack growth prior to mass wasting events. Under this scope, seismic signal is at the same time a tool for crack monitoring and a possible factor for crack growth. 
Thus, I try to address the following points:
1)What are the changes in seismic signal signature prior to a mass wasting event ? What can we learn on ground properties from that ?
2) How seismic ambient noise does impact slope stability and crack propagation ?
I use an interdisciplinary approach combining seismic signal analysis, ambient noise seismology and numerical/physical modelling.
