Summary
As women age, both the quality and quantity of their eggs decline and their chances of conceiving plummets. Premature ovarian failure (POF) is a disease of infertility, diagnosed in 3% of all women, defined by the early onset of menopause before age 40. Our poor understanding of the factors that regulate female egg supply remains a major limitation in treating POF. I will study key factors responsible for controlling egg number, with practical implications for POF diagnosis and treatment.
Xenobiotics - Oxidative Stress In The Mammalian Ovary

Summary
Synthetic chemicals called xenobiotics in the environment are capable of interfering with female fertility. Xenobiotics can trigger oocyte depletion of the ovary and infertility. Exhaustion of the oocyte population results in the menopause, loss of ovarian hormones and profoundly affects female health through increasing susceptibility to heart and bone disease. This research will characterise xenobiotic effects on the ovary and will lead to significant advances in reproductive healthcare.
Female Reproductive Health Preservation By Nicotinamide Adenine Dinucleotide (NAD+) And Sirtuin2 (SIRT2)

Summary
Cancer treatment can be severely toxic to women’s eggs. Increasing numbers of women who survive cancer therefore become infertile and prematurely deprived of hormonal support whilst still in their reproductive years. This project will use state-of-the-art techniques to interrogate newly uncovered pathways that can protect eggs from treatment-induced injury thereby greatly improving the quality of life for female cancer survivors.
Macrophages In Developmental Programming Of Reproductive Health

Summary
Programming of reproductive health in women begins long before sexual maturity. Development during childhood, puberty and adulthood produces a fully functional reproductive system capable of conceiving, gestating and nurturing a child. This project will investigate the role of immune cells known as macrophages in the reproductive system, and investigate how their disruption might influence developmental programming and have lifetime consequences for the reproductive health of the individual.

Summary
Mammalian eggs grow and develop in fluid filled sacks in the ovary called follicles. These structures nurture the egg for prolonged periods preparing it for ovulation and fertilisation. It has been known for some time that the quality of the follicular environment determines, in part, the developmental potential of the egg. Recent studies in mice have shown that the interaction between the egg and the follicle is in fact a two-way process, and that the egg is able to influence development of the ....Mammalian eggs grow and develop in fluid filled sacks in the ovary called follicles. These structures nurture the egg for prolonged periods preparing it for ovulation and fertilisation. It has been known for some time that the quality of the follicular environment determines, in part, the developmental potential of the egg. Recent studies in mice have shown that the interaction between the egg and the follicle is in fact a two-way process, and that the egg is able to influence development of the follicle. This project proposes to investigate these processes further in the laboratory mouse using new reagents available to us, and to extend these findings by investigating this communication pathway for the first time in a primate species. Because of the difficulty of undertaking such research using human material, we will use the marmoset monkey as a model. This exciting new development has important implications for women's health because it may help us understand why some women suffer from premature menopause or cystic ovaries, and in the longer term could help in the development of new types of contraceptives.Read moreRead less
Follicle-stimulating hormone (FSH) is vital for egg development, female fertility and health, and is widely used in assisted reproduction technology. But high levels of FSH are associated with premature infertility and menopause, and may lead to diseases like ovarian cancer. Understanding the biological pathways activated by elevated FSH may lead to new treatments for infertility and ovarian diseases (eg. cancer), as well as advancing new strategies for contraception.
Female fertility and age at menopause are determined by the number and quality of eggs stored in the ovaries. For unknown reasons, two-thirds of all eggs die soon after they are made. Furthermore, a serious side effect of cancer treatment is egg death resulting in infertility and early menopause. I am unravelling the genes involved in determining whether an egg will live or die. This understanding will help us develop novel strategies to preserve fertility during aging and cancer treatment.
Uptake of fertility preservation procedures (eg. egg and embryo freezing) prior to cancer treatment is increasing and women will return to use these to try to conceive. Radiation may damage the uterus and there is insufficient evidence to guide the management of those exposed to intermediate doses. The aim is to improve understanding of radiation effects on the uterus which will assist clinicians with deciding whether it can support a pregnancy, or if surrogacy should be advised.
I am a reproductive biologist focused on women’s reproductive health. I am studying the reasons why some women are infertile have spontaneous abortions and pregnancy complications such as pre-eclampsia. My research will define the roles of molecules that are critical in the establishment of pregnancy and the formation of a health placenta and therefore a healthy baby.
Facilitating Endometrial Receptivity To Improve Pregnancy Outcomes

Summary
The womb prepares itself in each menstrual cycle for pregnancy and the implantation of an embryo. In some women, the endometrium may not prepare itself adequately and this can lead to infertility. We have identified small RNA that may be useful in predicting which women are not adequately prepared for implantation and may be used to develop treatments for infertile women, for which there are currently no treatments.
