Reference: 35445 / SC 042 / 2024 


UCLouvain and the Royal Observatory of Belgium are looking for 

A full-time academic/researcher in Gravitational Wave Physics 


Main campus: Louvain-la-Neuve and Brussels (Uccle)

About us

UCLouvain is one of the world's top 1% universities. A comprehensive university located in the heart of Europe since 1425, it brings together 33,000 students and 6,000 members of staff on 8 campuses in Brussels and Wallonia. At UCLouvain, research and teaching are organised into 14 faculties, 22 research institutes, 5 learning centres and 18 libraries. It also has two university clinics.

The Royal Observatory of Belgium is a federal research institute (200 staff) located in the leafy suburbs of Brussels, working under the aegis of Belgian federal science policy. Its main areas of research are solar physics, astronomy and astrophysics, geophysics and reference systems. The Royal Observatory of Belgium is involved in several research areas that are directly linked or in strong synergy with the experimental physics of gravitational waves.

The position is open at both UCLouvain and the Royal Observatory of Belgium: it is a 50% academic position at UCLouvain and a 50% scientific position at the Royal Observatory of Belgium.  The person recruited must hold both positions; the expected activities will be carried out on the sites of both partners, at the level of 50% for each of them. This joint position, which involves strong interaction between the two institutions, is planned for a period of 10 years. At the end of this period, UCLouvain will take on the successful candidate on a full-time basis within its academic framework.
