Prof. Dr. Stephan A. Sieber
Academic Career and Research Areas
Prof. Sieber (*1976) conducts research in the field of bioorganic chemistry with the aim of developing new drugs against multi-resistant bacteria. The research is based on methods ranging from synthetic chemistry, functional proteomics and cell biology to mass spectrometry. This approach has already led to the discovery of new active substances, some of which are currently being optimized for medical application.
Prof. Sieber studied chemistry at the University of Marburg and completed his PhD thesis in the laboratories of Prof. C. T. Walsh at Harvard Medical School and Prof. M. Marahiel at the University of Marburg (2004). After a post-doctoral stay at the Scripps Institute with Prof. B. F. Cravatt (2006), he started his independent research at LMU Munich, funded by the DFG Emmy Noether program. In 2009, he received an appointment at TUM the chair of Organic Chemistry II. In 2010 and 2017 he received an ERC Starting Grant and an ERC Consolidator Grant.
