Postdoc
Joined the lab: January 2017
Background and Current Projects: I graduated in chemistry at the University of Hamburg. During my master’s degree I visited the Poul Nielsen group at the University of Southern Denmark for a research project based on the synthesis of double-headed nucleosides using Sonogashira-couplings. Afterwards I joined the research group of Andrea Rentmeister for my master thesis focussing on the diversification of the substrate spectrum of trimethylguanosine synthases. For my doctoral thesis I followed Andrea Rentmeister to the University of Münster to establish a chemo-enzymatic approach for labelling the 5’ cap of eukaryotic mRNAs via bioorthogonal click reactions. In January 2017 I joined the group of Florian Hollfelder as a PostDoc to work on the screening of metagenomic libraries for non-natural enzyme activities using microfluidic droplet systems.
Interests: In my free time I enjoy running, doing pilates and yoga, and I like playing the piano.
