Melanoma treatment has been revolutionised by the advent of immune check point inhibitors (ICIs). However, only 50% of patients will respond to the treatment. A promising alternative for those who ICI is ineffective is tumour infiltrating lymphocyte (TIL) therapy, an innovative form of immunotherapy that involves extraction, expansion and infusion of a patient’s specific immune cells (T cells). In an Australian first, the PERTIL trial, led by Prof Elin Gray, will be treating ICI resistant melanoma patients with TIL therapy. Predicting who will benefit from TIL therapy will be an important complementary work to the PERTIL trial.

Our team has shown the value of circulating tumour DNA (ctDNA) as a blood-based biomarker for melanoma. Plasma-derived ctDNA can be distinguished from normal cell free DNA (cfDNA) by differences in biology, including fragment length and tumour-induced DNA lesions. Thus, this project will leverage ctDNA genomics and bioinformatics to predict patients that would benefit from TIL therapy.

Specific Aims: 1) Construct a machine learning model of cfDNA features which can predict response to TIL therapy at baseline. 2) Longitudinally monitor patients for markers of treatment response and resistance using cfDNA.

Expected Outcomes and Impact: The development of a novel biomarker that could be used to predict which patients will benefit from TIL therapy. The successful completion of the project will provide clinicians with more information regarding the success of TIL therapy prior to administration.

Preferred applicant: We are looking for a HDR applicant with extensive wet lab experience in cfDNA extraction, library preparation and next generation sequencing. We also expect that the student is proficient in both windows and linux operating systems, as well as having previous experience with bioinformatics analysis using R, python and command line.

Although metastasis is the foremost cause of cancer-related death, a specialized mechanism that reprograms anchorage dependency of solid tumour cells into circulating tumour cells (CTCs) during the metastatic cascade remains elusive. The Adherent-to-Suspension Transition (AST) has been proposed as a reprogramming of adherent cells into suspension cells via the aberrant induction of hematopoietic transcriptional regulators, which are hijacked by solid tumour cells to disseminate into CTCs.

Here we aim to investigate melanoma dissemination by using a synthetic epigenetic reprogramming approach to alter AST factors. The project will use mouse models and de novo metastatic patient specimens to uncover how Adherent-Suspension Plasticity (ASP) dictates anchorage plasticity during the dissemination and colonization process within the metastatic cascade.

Expected Outcomes and Impact: The results will uncover therapeutic strategies that target AST factors that can be deployed to abrogate CTC formation and suppress distant metastases specifically.

These findings will underscore an important early mechanism by which cancer cells spread and highlight novel targets for the development of anti-metastatic therapies.

Preferred applicant: We are seeking a highly motivated and diligent HDR applicant who has demonstrated the capacity to work independently. A background in cancer research, genetic engineering and molecular biology is required.

Highly desirable skills: Experience in working with animals and managing animal research ethics Experience with bioinformatics analysis using R, python and/or command line.

This project aims to explore the expectations and perceptions of what a genetic test can provide from the perspective of people seeking out private genetic testing. Exploring what people perceive genetic testing can do will allow for a greater understanding of the gap between current technology and expectations (Masters by Research project).

This project aims to examine patient satisfaction with private genetic counselling services across all areas of service, i.e. familial cancer, reproduction, adult, paediatrics and pharmacogenomics. Demonstrating patient perspectives and satisfaction may drive change within the industry leading to better healthcare outcomes in genetic health of the population (Masters by research project).

This research program investigates the interaction of genetics and lifestyle/modifiable risk factors (sleep, physical activity, diet, and metabolic factors) in the context of Alzheimer's Disease with the aim of furthering our understanding of gene-lifestyle interactions (Lifestyle Genomics (LGx)) and development of individualised lifestyle interventions and preventative strategies.

The overarching aim of this study is to assess the clinical utility of blood derived biomarkers such as circulating tumour cells (CTCs), circulating tumour DNA (ctDNA) and extracellular vesicles for predicting and monitoring response to immune checkpoint blockade in melanoma and lung cancer. It is expected that a suitable candidate has a background in bioinformatic analysis.
