Johann is a postdoctoral fellow in the Tothova lab. He completed his MD in Daniel Nowak’s lab at the University of Heidelberg, Germany studying the clonal dynamics of patients with myelodysplastic syndrome. While completing his clinical training in internal medicine at the University Medical Center Mannheim, Germany, he developed both wet lab and bioinformatics skills for genome-wide mutational and transcriptional analysis to support clinical decision making for patients with MDS and AML. In the Tothova lab he is interested in studying how cohesin mutations confer competitive advantage to stem cells leading to the clonal dominance and in ways to tackle them therapeutically. Outside the lab, Johann’s two toddlers keep him busy, he is a passionate cyclist and looks forward to resuming his activity as a semi-professional singer after the pandemic.
