Florian Grebien did his PhD jointly supervised by Ernst Müllner of the Medical University Vienna and Hartmut Beug of the Research Institute for Molecular Pathology (IMP) in Vienna. For his post-doctoral research he joined the team of Giulio Superti-Furga at the Research Center for Molecular Medicine (CeMM), Vienna. From 2014 to 2018, he was a Principal Investigator and group leader at the Ludwig Boltzmann Institute for Cancer Research (LBI-CR) in Vienna. In January 2018, he was appointed Professor and head of the institute for Medical Biochemistry at the University of Veterinary Medicine Vienna.

Florian Grebien’s research focuses on acute myeloid leukemia (AML), a cancer of white blood cells that is characterized by the rapid growth of abnormal myeloid cells that accumulate in the bone marrow and interfere with the production of normal blood cells. The Grebien laboratory aims to contribute to a better understanding of the molecular mechanisms of leukemia development. We study cellular and molecular effects of leukemia-associated oncoproteins through the development and use of novel tools, including cell culture and mouse models, Next Generation Sequencing, Mass Spectrometry and primary patient samples.
