Kürşad Turgay studied Chemistry at the TU Berlin and received his Dr. rer. nat. from the Philipps University Marburg, where he worked with Mohamed Marahiel on non-ribosomal peptide synthetases. For his postdoctoral research he went to David Dubnau's lab at the Public Health Research Institute then in NYC, where he worked on the control of competence development by regulated proteolysis in Bacillus subtilis. Next he joined the lab of Bernd Bukau - first at the University of Freiburg and then at the ZMBH of the University of Heidelberg - to continue his studies on proteolysis.
Kürşad Turgay has since been a Junior Professor and a Heisenberg Fellow of the DFG at the Institute for Biology - Microbiology of the FU Berlin. He is a Professor of Microbiology here at the Leibniz University in Hanover.
