Interuniversity BOF projects (iBOF)

Interuniversity BOF-projects (iBOFAll Flemish universities jointly launch the iBOF-programme for the 3rd time in 2023, which cofunds interuniversity projects. Within the iBOF programme, excellent, pioneering (frontier or blue-sky) research is supported that will be carried out in a consortium of at least 3 promoters at at least 2 Flemish universities. The iBOF call is launched every 2 year.

An iBOF project brings together top researchers (whether or not in combination with promising researchers with great potential) who, through such an interuniversity project, will (further) promote Flanders at an international level by deepening or broadening scientific knowledge and increasing capacity building in a sustainable partnership.

The applying consortium must submit a concerted research proposal with a duration of 4 years, in which each promoter provides essential expertise for the realization of the proposal. At the same time, the promoters must be complementary to each other and/or mutually reinforcing as they need each other to be able to carry out the project in synergy. Proposals from all domains are possible, both mono- and interdisciplinary project proposals.


  • 4 years
  • duration of project: 1 January 2025 - 31 December 2028


The total amount that can be requested per promoter varies between 450.000 and 900.000 euro, with a maximum of 3.375.000 euro per consortium.
The requested budget has to be realistic and in accordance with the intended work packages.

Who can apply for an iBOF project?

  • At least one of the promoters is a top researcher with an excellent track record (see description ‘excellence’ in the call). The involvement of promising researchers with a great potential is also highly recommended;
