Research Overview
The Kaiser group develops and uses chemical biology approaches to investigate diverse aspects of regulated proteolysis and to study the molecular mechanisms behind bioactive small molecule action. Our interests are however not limited to basic research; rather, we aim to capitalize on our scientific findings for drug discovery or other medicinal applications.
