Research summary

Our mission is to develop preventive and therapeutic strategies for abnormal uterine bleeding (problematic periods). We aim to improve the quality of life of women, which will ultimately benefit wider society.

To achieve this, our clinical team and discovery scientists perform innovative research to enhance understanding of menstruation and associated disorders, collaborate globally, train the next generation of experts and engage with the public.

We have a particular interest in the cause of heavy menstrual bleeding, which has a severe negative impact on the quality of life of many women. We study the physiology and pathology of menstruation to develop new, acceptable treatments for women with heavy periods to minimise the need for fertility removing surgery.
