Welcome to the Laboratory of Biomolecular Research!


The goal of the research at the Laboratory of Biomolecular Research (LBR) within the Biology and Chemistry Division at the Paul Scherrer Institute is to provide an atomic level understanding on how the structure and dynamics of proteins and their complexes control essential biological processes. Our mission aligns with one of PSI’s main research focuses: The investigation of fundamental molecular mechanisms that determine human health and disease and exploring possible treatment methods.

In line with the mandate of the Division of Biology and Chemistry (BIO), we perform curiosity-driven, basic molecular biology research in the areas of cell division and signaling. Furthermore, we actively seek for possibilities to get engaged in applied research activities like, for example, drug discovery. Our research focusses on the structural analysis of challenging soluble and membrane-bound protein samples by using state-of-the-art X-ray crystallography techniques at the Swiss Light Source and SwissFEL, in combination with biophysical and modern electron microscopy methods.
