Paula Ypma is a hematologist in The HagaZiekenhuis in The Hague for over ten years now. Although, during her study Ypma was never much involved in research, the drive to be part of a scientific study was still there. So, since two years now, she spends one day a week on research; a clinical trial study performed by Sanquin.
