The Institute for Gravitational and Subatomic Physics (GRASP) at Utrecht University is looking for a highly motivated postdoctoral researcher in gravitational wave data analysis and phenomenology, who is interested in studying gravitational wave signals from coalescing binary black holes as probes of fundamental physics, specifically in the context of black hole mimickers.

At GRASP this effort is led by Professor Chris Van Den Broeck 

external link

 and Dr Anuradha Samajdar 

external link, and currently involves a team of 16 postdocs and PhD students. The group has close ties with researchers at Utrecht University’s Institute for Theoretical Physics, and with other individuals and institutes across the Netherlands as well as globally. Within the Netherlands this research will be carried out as part of the Dutch Black Hole Consortium, which includes more than 10 universities and knowledge institutes across the country. Internationally, the successful candidate will conduct her or his research as a member of the LIGO-Virgo-KAGRA Collaboration and the Einstein Telescope Collaboration.


You as a candidate are expected to have, or be in the final stages of obtaining, a PhD degree in Physics or a closely related field. Excellent programming and scientific writing skills are required, as well as English communication skills, together with the motivation to work in a multidisciplinary, international research team.


We offer:

  • a temporary position (1.0 FTE) for two years; 
  • a full-time gross salary ranging from € 3.226,- to €5.090,- in scale 10;
  • benefits including 8% holiday bonus and 8.3% end-of-year bonus;

A better future for everyone. This ambition motivates our scientists in executing their leading research and inspiring teaching. At Utrecht University 

external link

, the various disciplines collaborate intensively towards major strategic themes 

external link. Our focus is on Dynamics of Youth, Institutions for Open Societies, Life Sciences and Pathways to Sustainability. Sharing science, shaping tomorrow external link.

At the Faculty of Science 

external link

, there are 6 departments to make a fundamental connection with: Biology, Chemistry, Information and Computing Sciences, Mathematics, Pharmaceutical Sciences, and Physics. Each of these is made up of distinct institutes that work together to focus on answering some of humanity’s most pressing problems. More fundamental still are the individual research groups – the building blocks of our ambitious scientific projects. Find out more about us on YouTube

The Institute for Gravitational and Subatomic Physics (GRASP) 

external link

 aims at understanding the basic constituents of matter and their interactions, and the fundamental properties of space and time. Its members perform experimental research on heavy-ion collisions at the Large Hadron Collider, and gravitational wave data analysis related to neutron stars and black holes. We have ties with Utrecht University’s Institute for Theoretical Physics 

external link, and at the national level also with Nikhef, the National Institute for Subatomic Physics in Amsterdam, of which we are a consortium partner. We are actively involved in large international collaborations such as ALICE, Virgo, Einstein Telescope, and LISA.
