Johannes studied Medicine at the University of Tuebingen and the Technical University of Munich. His doctoral thesis at the University of Munich focused on the recognition of viral nucleic acids by the innate immune system. After graduating in 2011, Johannes started clinical training in the department of Hematology and Medical Oncology at the University of Munich (Head: Prof. W. Hiddemann) and soon developed a strong clinical and scientific interest in the biology of malignant lymphoma. Johannes joined the group of Dr. Oliver Weigert in 2013 and worked on the molecular characterization of specific subtypes of follicular lymphoma (FL) to elucidate general mechanisms of FL progression and transformation.
Johannes joined the Melnick lab in 2015. His current research focuses on the role of long non-coding RNAs in the pathogenesis of B-cell non-Hodgkin lymphoma (B-NHL). Johannes is supported by a Mildred Scheel Postdoctoral Fellowship (German Cancer Aid).
