Your responsibilities

Duties include academic services in the project named above. Research associates may also pursue further academic qualifications outside of their work responsibilities. They may also pursue doctoral studies outside of working duties.

The position is part of the project “RUBADO: Geothermal Reservoir Monitoring and Seismic Imaging with Dark Fibers in the Upper Rhine Graben”, funded by the Federal Ministry for Economic Affairs and Energy of Germany (BMWE). RUBADO is a collaboration between the University of Hamburg, the Karlsruhe Institute of Technology and Geotomographie GmbH. RUBADO investigates the innovative use of seismic sensing networks and distributed acoustic sensing (DAS) on existing urban and rural fiber-optic infrastructure for the high-resolution monitoring and imaging of geothermal reservoirs. The project aims to advance cost-effective, minimally invasive, and scalable techniques for subsurface characterization, reservoir safety, and long-term environmental stewardship in geothermally active regions. RUBADO focuses on existing geothermal infrastructure in the Upper Rhine Graben, leveraging extensive telecom “dark fiber” networks to set new standards in geoscientific imaging and monitoring, supporting the sustainable development and societal acceptance of geothermal energy solutions.

The position is situated within the seismology group at the Institute of Geophysics, University of Hamburg. The group specializes in ambient noise seismology, passive imaging, seismic interferometry, distributed acoustic sensing, and modern data-driven analysis techniques, including machine learning. Research focuses on understanding seismic noise sources, imaging near-surface and crustal structures, and monitoring structural changes in Earth materials.

The successful candidate will focus on the development and application of passive seismic imaging methods using ambient seismic noise recorded on dark-fiber DAS networks. The primary research objective is the determination of shallow and intermediate-depth subsurface structures along several DAS deployments in Karlsruhe and the Upper Rhine Graben. Tasks include the development, implementation, and testing of advanced methods for beamforming and surface-wave tomography, the inversion of frequency-dependent measurements to derive S-wave velocity profiles (e.g., VS30), and the integration of ambient-noise interferometry to generate tomographic models along the fiber-optic lines. The successful candidate will actively collaborate with project partners, validate DAS-based results using classical sensor networks, and contribute to the development of open-source workflows.

Responsibilities further include contributing to field deployments of seismic sensors, participating in project meetings, presenting research at international conferences, preparing publications in peer‑reviewed journals, and contributing to open-science dissemination efforts within the RUBADO consortium.

The successful candidate may become a member of the School of Integrated Climate and Earth System Sciences (SICSS), which supports doctoral researchers through training, mentoring, and career development.
