About us

Our research group is interested in understanding how RNAs change their structures in order to perform function. Until recently, only snapshots of molecules could be observed, hiding their mode of operation. We employ Nuclear Magnetic Resonance (NMR), and other biophysical techniques, to investigate the molecular mechanism of RNA function. When function of these molecular machines becomes apparent, it also provides a variety of unique new drug targets. The lab develops methods in NMR and RNA biochemistry to address these questions. Current projects include viral, bacterial and eukaryotic regulatory RNAs, e.g. microRNAs, ribosomal RNAs or RNA from HBV.
