PhD position in Gravitational Waves and Cosmology

Research / Academic

Nikhef has a PhD position in Gravitational Waves and Cosmology with an emphasis on signals from binary neutron star and neutron star-black hole coalescences.

Nikhef participates in large research collaborations, including the ATLAS, LHCb and ALICE experiments at CERN, the KM3NeT neutrino telescope in the Mediterranean, the VIRGO interferometer in Pisa, the Xenon1T dark matter experiment in Gran Sasso, the Pierre Auger cosmic ray observatory in Argentina and the eEDM research programme in Groningen. Nikhef also hosts a group in theoretical physics, and groups for Physics Data Processing and detector R&D, all with good connections to the experimental programs.

What are you going to do?

While the successful candidate will be employed by the Institute of Physics, University of Amsterdam, you will be fully embedded in the Gravitational Waves group at Nikhef. The emphasis of the position is on using signals from coalescing binary objects (neutron stars and/or black holes) as 'standard sirens' for cosmological measurements. The successful candidate will work with the groups of Prof. Chris van den Broeck (Nikhef and Utrecht University), and of Dr Samaya Nissanke (Nikhef and University of Amsterdam). The gravitational physics division at Nikhef (led by Prof. Frank Linde) has close ties with gravitational wave researchers at universities and institutes across the Netherlands, which apart from instrumentalists includes astronomers, astrophysicists, and theorists, such as Baumann, Bertone, Caudill, Groot, Hinderer, Jonker, Levan, Moesta, and Nelemans. There is also vibrant collaboration with individuals and groups around the world.


You have a master’s degree in Physics or a closely related discipline. Excellent analysis skills and an analytical mind-set, as well as excellent communication skills, including written English language proficiency are required. You have an ability to work independently and as a member of a research team. A collaborative attitude is strongly desired.

Salary Benefits:

Our offer

A temporary contract for 38 hours per week for the duration of 4 years (initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years) and should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.

The salary, depending on relevant experience before the beginning of the employment contract, will be €2,395 to €3,061 (scale P) gross per month, based on a full-time contract of 38 hours a week. This is exclusive 8% holiday allowance and 8.3% end-of-year bonus. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants.
