Professor John Evans is studying gynaecological cancers in collaboration with Peter Sykes. These investigations aim to understand cancers and develop new treatments.

Another set of studies investigates the regulation of the ovulatory cycle. This research is aimed at developing methods of fertility modulation.

Previous investigations of the peptides in cells lining blood vessels have provided new information on vascular disease.
