Prof. Dr. Celine Hadziioannou

Affiliation: University of Hamburg
Website: celine.hadzii.com, UHH Seismology
Publications: Google scholar
Interests: Prof. Dr. Celine Hadziioannou is fascinated by exploring the information contained in seismic signals recorded in the absence of earthquakes, during seismically quiet times. Usually, these signals, which compose over 90% of seismic recordings worldwide, are discarded as ‘noise’. It turns out, however, that they consist of seismic waves, which carry the imprint of the sources that generated them, and of the material that they passed through.
Prof. Hadziioannou is interested in “listening” to this noise with new sensor types such as DAS, using it to monitor changes in the subsurface and buildings, and understanding the sources of seismic noise.
Collaborations: SPIN, an Innovative Training Network (ITN) funded by the European Commission (Horizon 2020), which focuses on using the latest ground-motion sensing technology to improve the monitoring of geohazards.


Prof. Dr. Oliver Gerberding

Affiliation: Institut für Experimentalphysik, University of Hamburg
Website: Gravitational wave detection
Publications: Google Scholar, ORCID
Interests: Oliver Gerberding works on reducing seismic and control noise in gravitational wave detectors with the help of compact interferometers and inertial sensors. He studies methods to use distributed acoustic sensing to optimise seismic isolation systems in current and future detectors. His group also investigates methods to reduce the influence of scattered light in laser interferometers.
In addition, he also works on developing technologies for space-based detectors like LISA and moon-based detectors like the Lunar Gravitational Wave Antenna (LGWA).
Collaborations: LIGO-Virgo-Kagra Collaboration, Einstein Telescope Collaboration, LISA Consortium, LGWA Collaboration


Antonia Kiel

Affiliation: Institute of Geophysics, University of Hamburg
Interests: Antonia Kiel works in the field of seismology and machine learning. In the context of the CLICCS excellence cluster of the University of Hamburg, she worked on monitoring shallow groundwater in the urban area using ambient seismic noise. Using the distributed acoustic sensing data of the WAVE project, she compared different unsupervised clustering methods to detect different noise sources at the fiber, coming up with a workflow under what circumstances a particular clustering method should be used.
Collaborations: CLICCS


Dr. Alexander Bauer

Affiliation: Institute of Geophysics, University of Hamburg
Website: Researchgate
publications: Google Scholar
Interests: With a methodic background from exploration seismology, Dr. Bauer has spent the past decade working on seismic data characterization by means of wavefront attributes, tomographic velocity model building and wavefield separation - the latter mainly for the separation of reflected and diffracted (scattered) wavefields. Most recently, Dr. Bauer has utilized machine learning methods for wavefield separation and for the prediction of earthquake waveforms.
Collaborations: ErUM-WAVE




Dr. Holger Schlarb

Affiliation: Deutsches Elektronen-Synchrotron (DESY)
Website: Machine Beam Control group, desy.de
Publications: Scientific Journal Articles, ORCID
Interests: Holger Schlarb and his group MSK are responsible for the longitudinal and transverse beam stabilization systems of accelerators at DESY, covering a wide field ranging from femtosecond synchronization, special beam diagnostics, precision, real-time RF and beam feedback controls. Since environmental impacts of seismic and acoustic noise on accelerators can be severe, even a limiting factor for certain accelerator parameters, research using seismometer and iDAS to better understand, to be able to predict and ideally to mitigate vibrational noise source has become a new research focus in the accelerator beam controls group MSK.

Prof. Dr. Katharina-Sophie Isleif

Affiliation: Institute of Automation Technology at Helmut Schmidt University
Website: Metrology Group
Publications: Google Scholar
Interests: Prof. Dr. Katharina Isleif is a physicist engaged in the field of gravitational wave detection. Specifically, she focuses on modeling and mitigating Newtonian noise using seismic sensor networks for the "Einstein Telescope“, a next-generation gravitational wave detector planned in Europe. By advancing broadband seismic fiber sensors through precise laser interferometry, she contributes to the refinement of technologies for seismic measurements at frequencies below 10 Hz.
