Research Interest
Our group is interested in elucidating the mode-of-action of bioactive compounds, in particular of natural products. To this end, we use preparative organic chemistry as well as chemical proteomics to synthesize, rationally modify and finally to identify the targets of natural products.

Natural product synthesis, (chemical) proteomics, activity-based protein profiling (ABPP), protein expression, enzyme assays
