Lars Bullinger, MD, from the University Hospital of Ulm, Ulm, Germany, talks to us about HARMONY: An EU project in hematology, enabling a better and faster treatment for patients with hematological malignancies. He mentions the goal of HARMONY is to establish a platform where we can accumulate a large amount of data sets per disease group. This will allow us to start capturing the molecular heterogeneity of the disease and therefore improve outcome for patients. Recorded at the European Hematology Association (EHA) 2017 Annual Congress in Madrid, Spain.
