I have studied Biochemistry at Universität Leipzig. In my Diploma thesis I started to use computer simulations (quantum chemistry) to study structure formation in non-natural peptides. I continued along these lines in my PhD studies, also in Leipzig. During a PostDoc stay at BIOTEC of TU Dresden, I started using empirical models (a.k.a. force fields) and dedicated myself to the development of structure search techniques with a focus on molecular docking. My next stop then was in Shanghai. With a Lynen Postdoc fellowship by Humboldt Foundation, I had the chance to investigate regulatory mechanisms and function of the blood protein von Willebrand factor, a key molecule in primary hemostasis. Since 2010, I am a scientist at Fritz Haber Institute (FHI) of the Max Planck Society, since 2013 I serve as a group leader in Matthias Scheffler's Theory department at FHI. Our work here deals with biomolecules in thin air (i.e. theoretical gas-phase spectroscopy of peptides and carbohydrates), large-scale overview studies on amino acid-cation structures, and organic reactions. Recently we started to also investigate biomolecules on metal surfaces. I am involved in the organization of meetings and summer schools, most importantly the Hands-On-DFT-and-Beyond series. I am also teaching at Freie Universität Berlin, where I was granted habilitation and venia legendi in 2016/17. Currently, I am a visiting professor at Universität Leipzig, acting as Chair for Theoretical Chemistry.
