Postdoc Position in Theoretical Astroparticle Physics, Cosmology and Machine Learning

Faculty/Services:  Faculty of Science
Educational level:  PhD
Function type:  Academic Staff
Closing date:  8 December 2022
Vacancy number:  10800



We invite applications for a postdoctoral research position at the GRAPPA (Gravitation Astroparticle Physics Amsterdam) center of excellence, at the University of Amsterdam (UvA). The position will start in fall 2023 and will be for the duration of two years (with a possible extension of another year depending on funding). The research interests of GRAPPA include multi-messenger astrophysics, dark matter and dark energy, the early Universe, gravitational waves and strong gravity.


You will work on central research questions in dark matter phenomenology, new physics searches and cosmology, in collaboration with Christoph Weniger and postdocs and PhD students of his group.  The group plays a leading role in the development and application of deep learning-based data-analysis methods, in particular simulation-based inference. This approach allows to significantly improve and simplify the analysis of complex astrophysical and cosmological data and detailed physical models (see and recent publication list for examples for possible projects). The group has ties to the Dutch eScience center, AI4Science, and AMLab.


You are also encouraged to collaborate with other GRAPPA faculty (Ben Freivogel, Daniel Baumann, Gianfranco Bertone, Jacco Vink, Patrick Decowski, Philipp Moesta, Samaya Nissanke, Sera Markoff, Shin’ichiro Ando). GRAPPA is connected to the Institute of Physics and the Anton Pannekoek Institute at the University of Amsterdam as well as Nikhef. GRAPPA also includes experimental physicists active in the Antares/KM3NeT, ATLAS, CTA, LOFAR, and XENON-nT collaborations.


Deadline: Submission deadline is 8th December 2022.


What are you going to do?


You will work in the group of Christoph Weniger, and be embedded in the GRAPPA Center of excellence in Gravitation and Astroparticle Physics, a multidisciplinary team of researchers active in a variety of research topics including dark matter, compact objects, high-energy astrophysics and physics beyond the standard model.


Tasks and responsibilities:

  • conducting independent research in theoretical astroparticle physics, cosmology and/or deep learning, resulting in academic publications in peer-reviewed international journals and/or books;
  • actively contributing to the research activities of GRAPPA;
  • (optionally) co-supervising Bachelor and Master theses and tutoring students; co-supervising PhD theses.


What do you have to offer?


Your experience and profile

  • You have a PhD in physics;
  • You are able to work independently and to collaborate in an collegial multidisciplinary research environment;
  • You are a committed researcher, demonstrated by publications in international refereed academic journals and academic publishers;
  • You have demonstrated abilities in theoretical physics, software and algorithm development, and/or astrophysical modeling.


Experience in deep learning are a plus but not required, and can be acquired as part of the position.


Our offer


We offer a temporary employment contract for 38 hours per week for a period of 2 years (with possible extension of a third year depending on the availability of funding. The preferred starting date is fall 2023.

This does not include 8% holiday allowance and 8,3% year-end allowance. The UFO profile name profile and level is applicable. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Universities of the Netherlands is applicable.


Besides the salary and a vibrant and challenging environment at Science Park we offer you multiple fringe benefits:

  • 232 holiday hours per year (based on fulltime) and extra holidays between Christmas and 1 January;
  • multiple courses on topics such as time management, handling stress and an online learning platform with 100+ different courses;
  • 7 weeks birth leave (partner leave) with 100% salary;
  • partly paid parental leave;
