Professor Frank von Delft works to ensure that X-ray structures can serve as a routine and predictive tool for generating novel chemistry for targeting proteins. In the process of drug discovery, X-ray crystallography is the most sensitive way to find out which compounds bind to a target protein. Recent advances in technology allow researchers to test many more compounds, much more rapidly. The ultimate aim is to bring much needed new treatments to patients.
