Dr. Michiel Rienstra and prof.dr. Isabelle C. Van Gelder are the group leaders and work closely together. Both divert their time between patient care and clinical research. The team consists of an bioinformatician who provides the statistical and bioinformatical support for all analyses. The other team members are all medical doctors (or in training), interested in research and working on their PhD thesis, before they start specialty training. They all have their own specific projects and clinical studies, but they work also closely together.
