The global initiative to complete the energy transition by 2040 puts tremendous pressure on governments and industries. The need for any nation to know the potential of its subsurface to meet the future demand for energy and raw materials, as well as its storage capacity (e.g. CO2, H2) and associated hazards (e.g. induced seismicity, subsidence), is more critical than ever for informing exploration efforts, strategic economic planning, environmental policies, and decision-makers.

The Netherlands has acquired a vast amount of geophysical data over the past 30 years. However, the formal integration and inversion of all available and complementary data have not been yet fully exploited for obtaining unifying, multi-parameter models of the subsurface. This project will develop novel ways of characterizing the physical state of the subsurface beneath the Netherlands via the formal integration of multiple geophysical (mainly seismological), geochemical/petrological and petrophysical data into a single physics-based framework. Specifically, we will establish a workflow to extract seismological observables from large seismological data sets using both existing and new Deep Learning (DL) techniques to be developed within the project. The retrieved seismological observables will be integrated with other available data sets (e.g. potential fields) and existing models to establish a common database to be inverted using an innovative multi-observable probabilistic platform. The new DL methods and workflow to extract high-quality seismic information will apply to similar data sets in other regions, opening new opportunities for analysing and using seismic records worldwide. Results will be disseminated through high-quality scientific publications, conference presentations and reports for a wide range of partners. Involvement in teaching and/or supervision of PhD projects related to the project is also expected.

You will collaborate closely with researchers at Utrecht University, KNMI, and Delft University of Technology. You will be a member of a large and dynamic geophysics/computational geodynamics team of PhD students and post-doctoral fellows.

Your project will be embedded in the Applied Earth Sciences department at the Faculty for Geo-Information Science and Earth Observation at the University of Twente. You will work together with the partners in the DeepNL INTEGRATION project to develop and generate new tools and models.

Your profile

  • You hold (or will soon hold) a PhD in seismology, geophysics, deep learning related to Earth sciences, computer science, physics, applied mathematics, or a related field
  • Good command of spoken and written English
  • Curiosity in geophysical datasets (e.g. seismic, potential fields, etc), and computer programming, e.g. with Python, MATLAB, C and/or Fortran
  • Curiosity in Numerical Methods for Partial Differential Equations, big data management and dealing with supercomputing facilities
  • Working with a major machine-learning framework (e.g. PyTorch, TensorFlow, JAX) and familiarity with geochemistry, inverse theory and/or thermodynamics are desirable but not essential
  • A socially engaged, independent and creative researcher with good conceptual, communication, problem-solving and organizational skills, and an interest in engaging in team-based collaborations

Our offer

  • An inspiring multidisciplinary, international and academic environment. The university offers a dynamic ecosystem with enthusiastic colleagues in which internationalization is an important part of the strategic agenda
  • A full-time position for 4 years
  • Gross monthly salary between € 3.720,- and € 5.090,- per month depending on experience and qualifications (UFO profile Researcher 4)
  • A holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.3%
  • Excellent support for research and facilities for professional and personal development
  • A solid pension scheme
  • A total of 41 holiday days per year in case of full-time employment
  • Excellent working conditions, an exciting scientific environment, and a green and lively campus

About the department

The department of Applied Earth Sciences combines earth scientific knowledge with dynamic modelling and advanced remote sensing, to analyse earth systems and processes in space and time. Our goal is to contribute to global challenges concerning future demands for earth resources and to help reduce disaster risk and the impact of natural hazards on communities living in changing environments.

About the organisation

The Faculty of Geo-Information Science and Earth Observation (ITC) provides international postgraduate education, research and project services in the field of geo-information science and earth observation. Our mission is capacity development, where we apply, share and facilitate the effective use of geo-information and earth observation knowledge and tools for tackling global wicked problems. Our purpose is to enable our many partners around the world to track and trace the impact – and the shifting causes and frontiers – of today’s global challenges. Our vision is of a world in which researchers, educators, and students collaborate across disciplinary and geographic divides with governmental and non-governmental organisations, institutes, businesses, and local populations to surmount today’s complex global challenges and to contribute to sustainable, fair, and digital societies.
