Summary
My work focuses on the endometrium, the lining of the uterus, into which the embryo implants to establish pregnancy. When the endometrium does not function correctly, the woman is usually infertile. Other disorders of the endometrium include endometriosis, menstrual bleeding problems and cancer. My studies have defined the molecular basis for much endometrial dysfunction. I am now developing non-invasive tests for these problems and rationales for new treatments.
Novel Roles For Follistatin In Reproductive Biology

Summary
The follistatin protein has important functions throughout the body. Recent studies using mutant mice have identified key roles for follistatin in the development and function of the female reproductive system (ovary, uterus). We will now undertake detailed studies to determine how follistatin regulates these processes. This is relevant to our understanding of the mechanisms causing infection and inflammation in the reproductive tract.
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.

Summary
~15% of couples are unable to have children. Their reliance on reproductive technologies (eg, IVF) has increased 4 fold over the past decade. One reason for infertility is that the lining of the uterus (endometrium) is not able to allow an embryo to attach – a key event in establishing healthy pregnancy. There is no test to assess whether the endometrium is ‘receptive’ to an embryo. We will develop special assays for a test and provide a basis for treatment without recourse to IVF.

Summary
The womb is essential for a health pregnancy. This research aims to determine how the womb interacts with embryos to ensure a healthy pregnancy forms. Cells in the womb can also grow abnormally and result in endometrial cancer. New treatments for endometrial cancer will also be tested in this research.
Targeted Disruption Of Lipoxygenase Enzymes To Prevent Oxidative Stress-mediated Pathologies In The Male Germline

Summary
An estimated 80 million individuals suffer from infertility globally with at least 50% of these cases due to defects in sperm function. Unfortunately, due to a severe lack of knowledge surrounding sperm biology and dysfunction, no successful curative or preventative measures have been established. My project will study why sperm cells die and investigate new ways to limit cellular stress so we can develop new therapeutic strategies to mitigate the growing problems in male reproductive health.
Role Of The Anaphase-Promoting Complex Activator Cdh1 In Oocyte Maturation And Meiotic Aneuploidy

Summary
Eggs containing an incorrect number of chromosomes are described as aneuploid. This project sets out to examine the molecular causes of aneuploidy and why it increases with female age. We focus on the protective role of the protein Cdh1 in this process. The outcome would be to better understand the origins of aneuploidy so as to find methods of decreasing it as women age. This is highly significant given aneuploidy is the leading cause of early embryo loss and produces Down Syndrome babies.

Summary
To discover novel regulators of male fertility, we have screened libraries of mutant mice generated by a chemical mutagen. This project aims to define the function of the mutated gene identified in a male-specific infertile mutant mouse line. The mutated gene has been proposed to play a role in regulating cell death and suppress lung tumour formation. Our data may reveal novel options for male infertility treatment and for the development of male contraception and lung cancer biomarkers.
