PhD Position Advanced Stochastic Seismic Inversion and Testing to Capture Variability of Damping Ratio in Soil for Accurate Site-response Analysis – Delft University of Technology (TU Delft) – Delft

  • Delft

Delft University of Technology (TU Delft)

The PhD position will be in the Section of Applied Geophysics and Petrophysics and is part of a multi-disciplinary research project funded by the Dutch Research Council (NWO) as part of the DeepNL research initiative Call 2b ().

As a PhD candidate you will be working in the geophysics group and will develop advanced seismic data-inversion schemes to obtain spatially varying, reliable damping-ratio estimates in soil, taking also into account measurement errors. This research will build on ongoing work on full-waveform inversion and machine learning for laterally varying, high-resolution shear-wave velocity and geotechnical information. The final goal is to facilitate a more realistic earthquake site-response analysis through incorporation of 3D heterogeneities in soils. You will interact closely with the other PhD candidate to achieve this goal. See our other vacancy as well .

You will be responsible for developing a novel stochastic inversion scheme for damping ratio estimation from surface-wave dispersion data together with input from full-waveform inversion, testing the methodology on integrated active- and virtual-source seismic data, performing field tests, and estimating uncertainties. You will benefit from the ongoing 3DSOIL project and the recently completed SOFTTOP project (collaborative projects within DeepNL)

    The successful applicant should possess a very good first degree in Applied Geophysics, Civil Engineering or a related field, a strong background in mathematics, and training in seismic inversion/imaging. An affinity for computer programming is essential. This includes skill in implementing/adapting advanced inversion and imaging algorithms and working with different kinds of datasets. Aside from seismic imaging and inversion, it is essential that the student is interested in and has a strong aptitude for statistical/probabilistic methods. Also affinity to do both field- and lab-based research is an essential requirement. The successful candidate is expected to cooperate closely with other members of the DeepNL research team and with colleagues from both geophysics and dynamics of solids and structures backgrounds.

    Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the .

    Faculty Civil Engineering & Geosciences

    The Faculty of Civil Engineering & Geosciences (CEG) is committed to outstanding international research and education in the field of civil engineering, applied earth sciences, traffic and transport, water technology, and delta technology. Our research feeds into our educational programmes and covers societal challenges such as climate change, energy transition, resource availability, urbanisation and clean water. Our research projects are conducted in close cooperation with a wide range of research institutions. CEG is convinced of the importance of open science and supports its scientists in integrating open science in their research practice. The Faculty of CEG comprises 28 research groups in the following seven departments: Materials Mechanics Management & Design, Engineering Structures, Geoscience and Engineering, Geoscience and Remote Sensing, Transport &; Planning, Hydraulic Engineering and Water Management.

    The Department of Geoscience and Engineering encompasses 5 sections: Applied Geology; Applied Geophysics and Petrophysics; Geo-engineering; Resource Engineering; and Reservoir Engineering. The present PhD project will be a collaboration between the Sections of Applied Geophysics and of Dynamics of Solids and Structures.

    The Section of Applied Geophysics and Petrophysics executes a programme of fundamental and applied scientific research and education in exploration, engineering and environmental geophysics and petrophysics (). The Section has 12 full-time and 4 part-time academic staff, and 38 PhD and postdoctoral researchers. The Section actively contributes to the IDEA League Joint Master’s Programme in Applied Geophysics, together with ETH Zurich and RWTH Aachen University. The Section has good computation facilities and advanced infrastructure and instruments for field and laboratory experimental studies. The Section of Dynamics and Structures ( has 2 full-time and 3 part-time academic staff, and 11 PhD and Post-Doctoral researchers. The Section has a world-class expertise in the dynamics of a very broad range of civil engineering structures. Research projects typically deal with vibration and wave propagation problems of those structures in the interaction with their environments (soil, sea, air). The Dynamics Section takes care of key courses in the BSc and MSc programmes Civil Engineering and in the MSc programme Environmental Engineering, both in the base of the programmes and in the specialisation parts.

    The work in both Sections is fundamental in nature but driven by application; it contributes to the development of a clean and sustainable society. Also, both Sections have very good links with the industry.
