I am a Postdoctoral Researcher in the Development and Epigenetics Laboratory (PI: Dr Adrienne Sullivan) at the South Australian Immunogenomics Cancer Institute (SAiGENCI) and the Adelaide Centre for Epigenetics. My PhD work was undertaken in the Genome Editing Laboratory at SAHMRI, under the supervision of Professor Paul Thomas, Dr Fatwa Adikusuma, and Dr Laurence Wilson (CSIRO, NSW).

Postdoctoral research: understanding the biology of mammary gland development, and its relationship to disease

I am excited to have joined the Development and Epigenetics Laboratory, situated across the South Australian immunoGENomics Cancer Institute (SAiGENCI) and the Adelaide Centre for Epigenetics (ACE), the University of Adelaide. In this role, I am working on developing and optimising in vitro methods for studying human mammary gland development, to better understand the developmental program and elucidate the closely linked mechanisms underlying breast cancer biology and aetiology. 

I am also continuing my work in optimising advanced genome editing techniques, and applying these technologies to engineer human embryonic and induced pluripotent stem cells to facilitate the generation of biologically relevant models of development and disease progression.

PhD research: The development of novel CRISPR/Cas9 gene editing therapies for autosomal dominant Retinitis Pigmentosa (adRP)

One of the most common inherited eye dystrophies, adRP is clinically and genetically heterogeneous, with causative mutations found in dozens of genes. adRP causes progressive degeneration of photoreceptors (light-sensing cells of the retina), eventually leading to blindness, for which there is currently no effective treatment. Using cutting-edge gene editing technology, I have developed a suite of CRISPR/Cas9 therapeutic strategies for the most common adRP gene variants, and validated my approach in pre-clinical models to enhance the translational potential of these strategies.

For this research, I was grateful to be supported by both a RTP Stipend and a CSIRO Synthetic Biology Future Science Platform postgraduate top-up scholarship.
