Biography

Professor Evan Simpson was Director of Prince Henry’s Institute (now Hudson Institute of Medical Research) from 1999 to 2006.

He is the Laboratory Director of the Victorian Breast Cancer Research Consortium. This consortium involves eight medical research institutes and was established in 1997 to conduct world class research into breast cancer.

Professor Evan Simpson is a world leader in the field of oestrogen biosynthesis. His work has focussed on the study of aromatase, the enzyme responsible for oestrogen biosynthesis.

His group was the first to clone the gene encoding aromatase, and to show that tissue-specific regulation was under the control of tissue-specific promoters. His research led to the concept that oestrogen action in post-menopausal women is due to local production in sites such as the breast, bone and brain. This has led to the development of drugs for breast cancer therapy which specifically inhibit aromatase expression in the breast but spare other sites where it serves a critical role, such as in the bone, brain and blood vessels.

Professor Simpson’s work also led to the creation of the first aromatase knockout (ArKO) mouse, which is a model of oestrogen insufficiency that compares with the phenotype of humans with natural mutations in aromatase. This resulted in the discovery of new and unexpected roles for oestrogens in both males and females, in particular the role of oestrogens in the maintenance of bone metabolism in men and the role of oestrogens in the regulation of energy homeostasis in both sexes.

His current research is focused on the role of oestrogen in several important health conditions, including obesity, diabetes, osteoporosis and, of course, breast cancer.
