Summary
The last 10 years have seen a revolution in our ability to sequence DNA and related molecules. This technological advancement has the potential to transform our knowledge of the mechanisms of development and disease. In order to harness the power of this technology, advances in analysis strategies and methods are critical to extract the important insights into these massive data sets. My research will lead the way in several major areas of bioinformatics research.

Summary
Cancer is the cause of 1 in 8 deaths worldwide. Cancer occurs due to errors or mutations in the DNA of normal cells. I will identify the mutations in tumour cells, which will tell us: i) How the tumour started and grew ii) How to treat the tumour and kill the cancer The work involves a variety of cancer types including mesothelioma, melanoma, oesophageal and breast cancer. The overall aim is to apply some of the research findings or approaches into patient care to improve patient survival.

Summary
Skeletal muscle diseases can result in death in infancy or cause life-long and significant physical disability. Many families do not have a genetic explanation for their condition. We will use established and new technologies to find the missing genetics causing these devastating diseases. Our work has world-wide impact for the patients and families affected by these diseases.

Summary
There has been an explosion of high-throughput DNA sequencing technologies in the past five years, which have the potential to completely revolutionise medicine and scientific research. Here we present a series of studies showing the successful application of this technology to children with genetic disorders of the central nervous system. This proposal seeks to expand this study to a large cohort of similarly affected paediatric patients.

Summary
Evolution is a hallmark of cancer. It underlies tumorigenesis, metastasis, disease progression, the emergence of drug resistance, and patient death. My research will develop the essential bioinformatics methods and computational models to understand cancer evolution using -omics data, and apply these to discover the molecular mechanisms that cause complex genome rearrangements; investigate the evolution of advanced melanoma; and translate our tools and discoveries into the clinical setting.
Neuronal Genome Mosaicism: A Molecular Component Of Cognition?

Funding Amount
$687,975.00
Summary
The brain is a complex and dynamic organ tasked with interpreting and responding to the world around us. My recent work has shown that mobile genetic elements, or 'jumping genes', cause changes in the DNA of brain cells, potentially altering how they work. During the course of this fellowship, I will examine how and when during life these DNA changes occur, whether they play a role in memory formation, and whether they contribute to neurodevelopmental and mental health conditions.
For Every Question, There Is An Answer: Application Of Genomic Sequencing And Functional Genomics For Disease Gene Discovery In Children With Orphan Phenotypes

Funding Amount

Summary
My PhD study will look closely at the genes in a family to see what is different and whether this difference is the cause of rare health problems. I will focus on children with highly unique conditions in which intellectual disability/developmental delay is a key feature. My study is important because if I can find the exact cause of rare genetic conditions, then I hope to improve the welfare of patients and families affected by these types of conditions.
Mechanistic And Functional Drivers Of Neochromosome Evolution

Funding Amount
$763,771.00
Summary
Neochromosomes are Frankenstein chromosomes--massive extra chromosomes that are stitched together from 100s of pieces of normal chromosomes. They are found in 3% of cancers, but are common in some types, such as liposarcoma. We have mapped their structure and found they form through punctuated chromosome shattering and gene amplification. We will investigate the precise molecular mechanisms that cause this and the recurrent transcriptional and epigenetic drivers lead to their formation.
Determining Shared Genetic Control Of RNA Transcription Across 45 Human Tissue Types

Funding Amount
$264,684.00
Summary
There is strong evidence that much of the genetic susceptibility to disease acts through altering way genes are turned into proteins via RNA transcripts. One important problem in using transcriptomic data to study diseases is that the genetic control of RNA transcription is known to vary between tissues. This study will use new methods and RNA data from 45 human tissues to show the degree of common genetic control for each RNA transcript between each pair of tissues.

Summary
Genomics is routinely used across many livestock and plant breeding industries. It is now practical, within certain considerations, to consider applying genomic selection to aquaculture breeding programs due to significant cost reductions in the last decade. Its use in aquaculture breeding programs is increasing and genomics has already been researched for oyster breeding by USC (Vu et al. 2021a; Vu et al. 2021b).

It is now practical, within certain considerations, to consider applying genomic selection to aquaculture breeding programs due to significant cost reductions in the last decade. Its use in aquaculture breeding programs is increasing and genomics has already been researched for oyster breeding by USC (Vu et al. 2021a; Vu et al. 2021b).
Genomic selection has the potential to reduce the cost of estimating breeding values, which presently is a costly and challenging exercise with SROs and also may potentially increase genetic progress and selection accuracy for the SRO BP. The research proposed in this application will evaluate if it is possible to increase genetic progress for the productivity traits of QX disease resistance and growth as well as the product quality trait of meat condition. Increased QX survival and growth are particularly important traits for the SRO industry at this current time due to Port Stephens, the second largest SRO producing estuary in NSW, reeling from the impact of QX disease outbreaks. Climate change resilience is a new trait being investigated for incorporation into the breeding program for industry to respond to this threat. We would also like to assess whether genomics can provide a pathway to increase selection for resilience.
This project has been developed in line with the Oysters Australia Strategic Plan 2020 and the FRDC R&D Plan 2020-2025. The outcomes from this project will assess the feasibility of increasing selection accuracy for traits that improve productivity (growth and meat condition) as well as reduce impacts caused by QX disease and climate change through breeding for resilience. The outcomes will assess the possibility to improve genetic selections for multiple traits such that oysters can be selected on their ability to adapt to new climate conditions, survive QX disease whilst having faster growth and better meat condition. Additionally, this project will build new knowledge skills and networks through a NSW DPI, The University of the Sunshine Coast and The University of New South Wales alliance as well as create post-doctoral study opportunities. These meet the goals in Program 1, 2 and 3 outlined in the 2020-2025 Oysters Australia Strategic Plan.
With respect to the FRDC R&D Plan 2020-2025, this project will build capacity and create knowledge through developing skills and networks between NSW DPI, The University of the Sunshine Coast and The University of NSW to breed oysters that offer oyster businesses greater profitability, reduced risk and that can adapt to changing environments.
This project will explore alternative methods to what is presently used for SRO breeding to assess feasibility of genomic selection and what might be required today to move towards genomic selection in the future. This project will start compiling a reference library for SROs that can be used in the future and promote innovation in SRO breeding to integrate the technology developed from this project. Moreover, costs associated with genomic selection are reducing which increases the value proposition for incorporation into the future. The ultimate success and transfer of outcomes from this project to end user beneficiaries will be through incorporation of these new technologies into the SRO breeding program. Objectives: 1. Collect tissue samples using non-lethal methods and tagging to identify oysters 2. Sequence the whole genomes of selected individuals at high read depth, which will serve as the genotype resource for the project 3. Identify the associations between genotypes and phenotypes and compile a list of genetic markers and the genes associated with QX survival, whole weight and meat condition to then use modelling (for genomic predictions) to give individuals breeding values Read moreRead less
