Summary
One in four pregnancies in Australia will end in miscarriage. Infertility affects about 15% of Australian couples and is highly correlated with increasing maternal age. In this study, we will use cutting edge single-cell genomic approaches to investigate the activity of mobile DNA elements or “jumping genes” as a previously unexplored cause of reproductive failure, including spontaneous miscarriage and age-related female infertility.
Schizophrenia affects 1 in 100 people, and yet its causes remain largely unclear. To improve understanding, treatment and management of the disease, the team performing this research will evaluate whether mobile DNA elements found in our genome are activated by stress and thereby alter how brain cells work in individuals affected by schizophrenia. They will also test whether mobile DNA can be blocked by drugs, perhaps revealing new strategies to treat the disease.

Summary
L1 elements are powerful mutagens encoded within the human genome that becomes active in epithelial tumours. I will define the broad effects of L1 elements on the evolution of chemoresistance, focusing on ovarian cancer as a model system. Ovarian cancer is characterised by a poor 5 year survival rate of ~40% with most tumours developing resistance. Understanding the impacts of L1 on this evolution will inform the development and selection of more effective treatments for ovarian cancer.
