Warum und woran ich forsche

My scientific interest is in the field of mechanistic analysis of (electro) catalytic systems for the development of novel and sustainable catalytic concepts and of electro chemical energy storage materials and systems. In my diploma thesis and doctoral thesis with Prof. Leitner and Prof. Klankermayer at the RWTH Aachen, I focused on the chemical synthesis of homogeneous catalysts and correlated their structural and catalytic properties using nuclear magnetic resonance (NMR) and density functional theory (DFT) calculations. During my scientific visits to Prof. Bouchard at the UCLA and Prof. Blümich at the RWTH, I deepened my knowledge in NMR and catalysis on the subject of catalytic hyperpolarization using parahydrogen. While I was in the group of Prof. Schlögl at the MPI for Chemical Energie Conversion I deepened my knowledge of the development of heterogeneous (electro)catalysts and their characterization using in-operando NMR, dynamic nuclear polarization (DNP) and electron paramagnetic resonance (EPR). Now I am employed at the IET-1 in the group of Prof. Eichel and Prof. Granwehr. I continue my work on mechanistic analysis and development of novel materials and novel in-operando methods. Here I am particularly concerned with dynamic interface processes in heterogeneous electro(catalytic) systems.
