As a hematologist I am always looking for new development that might improve patient care. My main research focus is on patients with Hodgkin lymphoma and multiple myeloma. I am involved in both translational and clinical studies. In cooperation with the Pathology, I am active in the field of biomarkers, such as TARC in Hodgkin lymphoma. For the design, development and execution of clinical trials, I am an active member of both international (EORTC) and national (HOVON) organizations. For example, I am the national PI of the EORTC COBRA trial in Hodgkin lymphoma. Moreover, I am co-PI of the translational research in two international trials. In addition, I am part of the Dutch guideline writing committee for Hodgkin lymphoma. In myeloma, I am investigating innovative treatment options to improve outcome.
