Epigenetic and neurobehavioural changes in a new mouse model of foetal alcohol spectrum disorders. Foetal alcohol syndrome involves changes in growth, skull structure, central nervous system defects and intellectual disabilities. This project will use a mouse model to study the underlying causes of this disorder, focussing on brain structure and function, and aim to identify markers that can be used for early diagnosis and treatment.
Epigenetics, environment, and evolution. This project will aim to understand how biological information can exist and be passed from one generation to the next without being encoded in the gene sequence, and also how our early environment can modify this so-called "epigenetic" information to alter disease risk.
Is 'junk DNA' involved in gene editing in human cells. Exciting results suggest that non-coding RNAs (ncRNA), some of which emanate from regions in the human genome traditionally known as “junk DNA”, actually function to regulate protein-coding gene transcription. The goal of this project is to explore the role of ncRNAs on a genome-wide level to determine those proteins involved in this process and to what extent this process results in directed genome editing. Knowledge of the ncRNA pathways m ....Is 'junk DNA' involved in gene editing in human cells.

The goal of this project is to explore the role of ncRNAs on a genome-wide level to determine those proteins involved in this process and to what extent this process results in directed genome editing. Knowledge of the ncRNA pathways may lead to a novel methodology to activate silenced genes as well as determine the role of ncRNAs in genome evolution.Read moreRead less
Epigenetic regulation of centromere and telomere chromatin. Epigenetics is a system that turns genes on and off without sequence alterations in the DNA. This process works by attaching chemical tags, known as epigenetic marks, to DNA. Centromeres and telomeres are chromosomal DNA domains essential for faithful chromosome segregation and genome stability. Their function and structural integrity are tightly regulated by specific epigenetic marks. This project aims to assess the functions of key ep ....Epigenetic regulation of centromere and telomere chromatin. Epigenetics is a system that turns genes on and off without sequence alterations in the DNA. This process works by attaching chemical tags, known as epigenetic marks, to DNA. Centromeres and telomeres are chromosomal DNA domains essential for faithful chromosome segregation and genome stability. Their function and structural integrity are tightly regulated by specific epigenetic marks. This project aims to assess the functions of key epigenetic factors including chromatin remodelers, histone variants and non-coding RNA in controlling centromere and telomere activity. The data should describe novel pathways that maintain the identity, transcription silencing, DNA replication fidelity and structural stability at these domains.Read moreRead less
The role of long non-coding RNAs in the epigenetic control of gene expression during endosperm development in plants. Elucidating the molecular events underlying the biology of seed development is important in both understanding plant development and in developing new methods to enhance the productivity and qualities of grain crops. In recent years it has become clear that various classes of non-coding RNAs have important roles in gene regulation. Of these non-coding RNAs, small RNAs (20-25 nucl ....The role of long non-coding RNAs in the epigenetic control of gene expression during endosperm development in plants. Elucidating the molecular events underlying the biology of seed development is important in both understanding plant development and in developing new methods to enhance the productivity and qualities of grain crops. In recent years it has become clear that various classes of non-coding RNAs have important roles in gene regulation. Of these non-coding RNAs, small RNAs (20-25 nucleotides) are beginning to be understood however less is known about the role and complexity of long non-coding RNAs. This project would identify new regulators of seed development that may lead to novel methods to increase grain yields, ultimately benefitting the Australian grains industry.Read moreRead less
Unraveling the chromatin networks that control T lymphocyte differentiation. The development of T cell responses is essential for fighting infection but in some cases T cells can also cause allergy and autoimmune diseases. Previous research has shown by understanding the complex chromatin circuitry that underlie T cell function, therapies can be designed to rewire harmful T cells.

The development of T cell responses is essential for fighting infection but in some cases T cells can also cause allergy and autoimmune diseases. Previous research has shown by understanding the complex chromatin circuitry that underlie T cell function, therapies can be designed to rewire harmful T cells. This project will use a multi-disciplinary approach that combines expertise in cutting-edge molecular techniques with unique mouse models and bioinformatics to develop a fundamental understanding of the chromatin architecture and epigenetic networks that control important steps of T cell differentiation during development, allergy and infection.Read moreRead less
Deciphering the genetic architecture of human complex traits. This project aims to develop statistical methods to integrate data from genetic studies of complex traits such as stature and cognition. Molecular phenotypes such as gene expression in large samples will be used to predict target genes and regulatory elements of those traits. Understanding the genetic basis of human complex traits is critical to longstanding questions in human and evolutionary biology. The project will also detect sig ....Deciphering the genetic architecture of human complex traits. This project aims to develop statistical methods to integrate data from genetic studies of complex traits such as stature and cognition. Molecular phenotypes such as gene expression in large samples will be used to predict target genes and regulatory elements of those traits. Understanding the genetic basis of human complex traits is critical to longstanding questions in human and evolutionary biology. The project will also detect signatures of natural selection in shaping the genetic variation in complex traits. The project will provide better understanding of complex traits in global populations and the history of human evolution, and will develop methods applicable in plant and animal contexts.Read moreRead less
Solving the puzzle of complex disease - genes and their interactions with the environment. Many human diseases are caused by the interplay of genetic predisposition (nature) and the environment (nurture); but their causes remain a mystery, since much past research has focused on these aspects in isolation. This project will aim to better understand these complex diseases using a multi-factorial approach that brings both nature and nurture together.
Ageing and the muscle stem cell niche. Adult stem cells are critical for repair and maintenance of tissues and ageing tissues show reduced stem cell function. This project will focus on how ageing leads to disruption of communication between muscle stem cells and their niche. The project aims to identify new therapeutic targets for age-related muscle wasting and reduced mobility in the elderly.
Advancing our understanding of plant responses to low phosphorus availability beyond the transcriptome. Phosphorus is essential for plant growth. Plants have evolved mechanisms to cope with the poor availability of phosphorus in many soils. This project will improve Australia's knowledge of how plants alter the expression of genes and proteins to activate their mechanisms for coping with poor phosphorus availability in some soils.
