Kolff+ Programma 2026

The Dutch Kidney Foundation supports various grant types within the Kolff+ Program. The Program promotes creativity, talent and following up on successful research within a strategic framework that is directed at impact for the patient. The program consists of 2 calls per year with 3 different grant types in open competition: Creativity, Junior / Senior Talent and Success Accelerator Grants.
