Evolution of sensory systems in the dark biosphere. This project utilises a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. We aim to characterise and investigate the evolution of chemosensory and circadian rhythm genes, which play critical roles in the fitness of animals, including the ability to find food and mates in a ....Evolution of sensory systems in the dark biosphere. This project utilises a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. We aim to characterise and investigate the evolution of chemosensory and circadian rhythm genes, which play critical roles in the fitness of animals, including the ability to find food and mates in a dark, thermally stable environment. Knowledge of chemosensory and circadian genetic systems and how they dynamically evolve is fundamental to a variety of fields, including the process of speciation and biological adaptation (for example, to permanent darkness, pollutants and insecticides).Read moreRead less

Summary
Tracing the epigenetic life-history of cells. Each cell of the human body contains identical genetic information that is activated in different ways to form varied cell types. This research aims to develop novel single-cell genomic technologies to explain the origins of different cell types. This project expects to discover the molecular mechanisms through which specialised cell types are formed, which has been difficult to decipher using existing methods. My novel approach will elucidate how a ....Tracing the epigenetic life-history of cells. Each cell of the human body contains identical genetic information that is activated in different ways to form varied cell types. This research aims to develop novel single-cell genomic technologies to explain the origins of different cell types. This project expects to discover the molecular mechanisms through which specialised cell types are formed, which has been difficult to decipher using existing methods. My novel approach will elucidate how a small population of seemingly homogenous cells can give rise to a myriad of types of cells. Tracing the life histories of cells across time should lead to broad applications including in developmental biology, neuroscience and immunology.Read moreRead less
Can we exploit mRNA modifications to control protein expression? Genes are encoded by DNA but are transcribed into a message called RNA before they can be translated into protein. RNA can be chemically modified at a gene-specific level, and this modification has been central to the success of RNA vaccines against COVID-19. Despite the importance of these modifications in cellular life and in biotechnology, the role of the most abundant RNA modifications is unclear. This project will investigate ....Can we exploit mRNA modifications to control protein expression?

RNA can be chemically modified at a gene-specific level, and this modification has been central to the success of RNA vaccines against COVID-19. Despite the importance of these modifications in cellular life and in biotechnology, the role of the most abundant RNA modifications is unclear. This project will investigate how we can exploit RNA modifications to modulate protein expression in a tractable single-celled organism with a small genome, Plasmodium. This information is important because understanding gene regulation is fundamental to all life, and the role of RNA modifications is emerging as integral to biotechnology.Read moreRead less
Nuclear RNA surveillance and its connection to splicing quality control. Due to the error-prone nature of RNA splicing, elaborate quality control processes ensure that only correctly spliced transcripts can leave the nucleus. It has long been known that incorrectly spliced mRNA transcripts are degraded by the nuclear RNA surveillance machinery, but how the RNA quality control machinery is connected to nuclear RNA surveillance is not known. This proposal aims to uncover the connection between the ....Nuclear RNA surveillance and its connection to splicing quality control. Due to the error-prone nature of RNA splicing, elaborate quality control processes ensure that only correctly spliced transcripts can leave the nucleus. It has long been known that incorrectly spliced mRNA transcripts are degraded by the nuclear RNA surveillance machinery, but how the RNA quality control machinery is connected to nuclear RNA surveillance is not known. This proposal aims to uncover the connection between these two important processes and will fill a significant gap in our understanding of how splicing quality control and nuclear RNA surveillance work. The project will also identify sequence features that trigger abortive splicing reactions and will thus help to improve the design of synthetic mRNAs.Read moreRead less
Assembling the building blocks in the blueprint of the embryonic head. This project aims to profile and impute the genome activity and validate the cellular and molecular mechanism underpinning the generation, in time and space, of diverse types of tissues that constitute the building blocks of the embryonic head. The knowledge gain enriches our understanding of the early steps of head formation during embryogenesis in the context of the niche conditions associated with the acquisition of progen ....Assembling the building blocks in the blueprint of the embryonic head. This project aims to profile and impute the genome activity and validate the cellular and molecular mechanism underpinning the generation, in time and space, of diverse types of tissues that constitute the building blocks of the embryonic head. The knowledge gain enriches our understanding of the early steps of head formation during embryogenesis in the context of the niche conditions associated with the acquisition of progenitor state, enhancement of lineage propensity, and driving early lineage differentiation. Expected outcome of this research on the developmental biology of a model organism provides a framework of the mechanism of establishing a blueprint of development that may be conserved across multiple mammalian species.Read moreRead less
