I am a reproductive physiologist investigating the nature and actions of hormones, particularly steroids and transforming growth factor-? superfamily members, regulating follicle growth and oocyte quality in the ovary, implantation and breakthrough bleedi
Endometrial Receptivity For Embryo Implantation: Proprotein Convertase 6 And Plasma Membrane Remodeling

Summary
Implantation of an embryo into the uterus is a key step in establishing pregnancy; it requires a receptive uterus (fertile soil) and a healthy embryo (seed). Implantation failure causes pregnancy loss and infertility, and is also a major limiting factor in IVF. We have established that proprotein convertase 6 (PC6) is a master regulator of uterine receptivity for implantation. We will investigate how PC6 works in a woman’s uterus, and how we can use this knowledge to improve implantation in IVF.
Successful establishment of pregnancy requires a viable embryo and a receptive uterus. The contribution that reduced uterine receptivity makes to human infertility is unknown. IVF patients with implantation failure will be investigated using different approaches to identify gene pathways that are altered in reduced uterine receptivity. This study could lead to a clinical test for uterine receptivity and help to improve fertility treatment options for women with repeated implantation failure.
Infertility affects one in six couples and is an extremely distressing, expensive and frustrating experience for those that it afflicts. Through gaining a better understanding of the molecular and cellular processes governing ovulation and early embryo development, this team will devise new therapeutic strategies to improve the reproductive health of Australian women.
Mechanisms Underlying The Generation Of Spontaneous Contractions In Human Uterine Muscle: Potential Therapeutic Target For Dysfunctional Labour

Summary
Successful labour outcome is critical for the health of mother and offspring. Contractions too soon, or when they fail during labour, have significant short and long term consequences for mother and baby. Our recent studies on tissue from women in labour suggested new possible mechanisms underlying the initiation of uterine contractions. We will now test these ideas with a view to identifying new therapeutic targets for manipulating labour contractions.
Interleukin 11 And Leukaemia Inhibitory Factor: Important Regulators Of Embryo Implantation And Placentation

Summary
Infertility, spontaneous abortion and pre-eclampsia are major clinical problems. Interleukin (IL)-11 and leukemia inhibitory factor (LIF) are critical for embryo implantation in mice but their roles in women are unknown. I will define their roles in the establishment of pregnancy and provide new critical information on their potential as targets for diagnostic and therapeutic tools for infertility and major diseases associated with pregnancy.
I am a reproductive biologist - reproductive immunologist investigating the role of the female immune response and its cellular and molecular agents in establishing pregnancy. My research spans basic science and clinical and commercial transfer, and aims to improve our understanding of the factors determining optimal reproductive health in women leading to better treatments for infertility and pathologies of pregnancy, and the best possible health outcomes for babies and children.
