Centre for Reproductive Health researcher, Professor Hilary Critchley, has been profiled by the American Journal of Obstetrics and Gynecology in recognition for her pioneering contributions to the field. Professor Critchley's work focuses on the biology of menstruation and the understanding of abnormal uterine bleeding (AUB), including heavy menstrual bleeding (HMB).Her research looks at the cascade of events that occur in cells of the endometrium that lead to its shedding, in response to the decrease of the hormone progesterone. She is interested in the complex dialogue between circulating steroid hormones and the many different cell types, including immune cells, that constitute the endometrium.Professor Critchley's work truly spans from bench to bedside; her research includes understanding how the hormone progesterone acts on the uterus and ways in which we might alter this, physical differences in endometrial tissue in individuals with abnormal menstrual bleeding, and has led clinical trials for treatments for heavy menstrual bleeding with the aim of providing treatment options for the often overlooked condition.She is currently chair of the Wellbeing of Women Research Advisory Committee and an ambassador for the World Endometriosis Society.You can read the full profile below.
