I have a strong interest in understanding the composition and pattern of ambient seismic noise and what we can learn from it about subsurface structures as well as the sources of ambient noise, which are often of oceanic or atmospheric origin (e.g., waves, storms, wind). Hence, seismic noise can help to monitor these systems passively and remotely. My current research focusses on linking conventional and non-conventional seismic methods (e.g., beamforming, interferometry), improving their computational performance, and thereby reducing experimental and financial costs for subsurface characterisation related to renewable energy targets.

– Seismic imaging
– Wave propagation in fractured media
– Geothermal reservoir characterisation
– Subsurface monitoring
I joined the Department of Geology and Geophysics of the University of Aberdeen, UK, in 2020 as a Lecturer in Environmental Seismology. I studied Geophysics at the University of Münster, Germany, before completing a PhD on “Source-receiver wavefield interferometry in scattering media” at the University of Edinburgh, UK, in 2015. In 2016, I secured a grant from the German Research Foundation (DFG) that allowed me to work as a postdoctoral researcher at Bochum University of Applied Sciences, Germany, on “Synthesis of passive seismic methods for geothermal applications”. From 2016 to 2020, I was an active member of the EU’s Horizon 2020 project “GEMex”, an interdisciplinary and international collaboration investigating two geothermal sites in Mexico.
