Valk Lab

The department of Hematology at Erasmus MC is involved in clinical and translational research aimed at the improvement of treatment and diagnosis of hematological malignancies. The department coordinates and participates in multicenter clinical trials (HOVON/SAKK) and has a major focus on the delineation of the biology of hematologic malignancies and the development of molecular diagnostics for these diseases. The aim of these programs is to dissect the cellular and molecular pathogenesis of these conditions and translate them to clinical practice.

Dr Valk’s main interest is unraveling the molecular heterogeneity of hematologic malignancies, in particular acute myeloid leukemia (AML). Using various genome-wide technologies, such as gene expression profiling, genotyping and next generation sequencing, Dr Valk revealed novel insights into the heterogeneity and biology of AML. His work has developed molecular biomarkers that are incorporated into routine risk-stratification and clinical care of AML patients. More recently Dr Valk has focused on the detection of molecular minimal residual disease in AML, clonal hematopoiesis and germline predisposition to myeloid malignancy.
