Examining the relationship between error processing, cognitive control and emotion: a cognitive neuroscience approach. The proposed research aims to contribute to current scientific thinking on how the processing of errors influences self-monitoring and cognitive performance. The ability to monitor one's cognitive performance deteriorates with normal ageing, and is particularly affected in a range of clinical conditions, where it is a reliable predictor of a poor prognostic outcome. This project ....Examining the relationship between error processing, cognitive control and emotion: a cognitive neuroscience approach. The proposed research aims to contribute to current scientific thinking on how the processing of errors influences self-monitoring and cognitive performance. The ability to monitor one's cognitive performance deteriorates with normal ageing, and is particularly affected in a range of clinical conditions, where it is a reliable predictor of a poor prognostic outcome. This project aims to clarify understanding of the cognitive and neural processes underlying self-monitoring, as an important first step to improving rehabilitation and management methods for age-related impairments such as Alzheimer's disease, and prominent mental health conditions such as schizophrenia.Read moreRead less
Using visual science to reduce the dangers of night driving. This project aims to develop novel tests of visual function relevant to the modern night driving environment.

This project aims to design, synthesise and characterise nanoparticles that can mediate the adverse effects of reactive oxygen species. The project expects to develop nanoparticles with tailored chemical functionality to modulate the concentration of reactive oxygen species and develop a platform technology for addressing conditions where reactive species are overproduced. The project will research how nanoparticles’ physicochemical properties affect their activity, and how they affect cellular function, tissue morphology and particle transport in a biological milieu. The project is expected to benefit the advanced manufacturing, veterinary and medical sectors and could lead to new chemotherapeutics.Read moreRead less
Assessing the physiological roles of ubiquitination in regulating neuronal ion channels, receptors and transporters. Significant alterations in the activity neuronal transporters and receptors occur during tissue injury and regeneration as well as in many neurodegenerative disease states. Modulation of the pathways that control these transporters is an emerging therapeutic target, however, the molecular basis of these control mechanisms remain poorly understood. The outcome of this project will ....Assessing the physiological roles of ubiquitination in regulating neuronal ion channels, receptors and transporters. Significant alterations in the activity neuronal transporters and receptors occur during tissue injury and regeneration as well as in many neurodegenerative disease states. Modulation of the pathways that control these transporters is an emerging therapeutic target, however, the molecular basis of these control mechanisms remain poorly understood. The outcome of this project will be a thorough characterisation of a novel regulatory paradigm in neurons that is likely to be crucial for neuronal development and regeneration, and will potentially provide novel therapeutic targets for various neuronal diseases.Read moreRead less

It will highlight a new approach to the therapeutic targeting of MYB in cancer: data generated from this research may enable us to target MYB expression in a range of cancers including breast cancer by inhibiting transcriptional elongation. And it will provide training in advanced molecular biology to postdoctoral scientists and students.Read moreRead less
Estrogen signalling in gonadotropes. Estrogen action is a normal prerequisite for cyclic function of reproduction in the female, but little is known about how this important hormone acts in the relevant cells of the pituitary gland (gonadotropes). In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studi ....Estrogen signalling in gonadotropes.

In order to gain information on normal function, we will conduct studies on gonadotropes treated with estrogen in a range of paradigms. The information will be valuable in understanding normal reproduction, but will also form the basis of further studies to investigate the effects of drugs that affect estrogen action and environmental estrogens.

Molecular genetic analyses of trinucleotide repeat expansions. Several neuronal diseases like Huntington's disease, Frederick's ataxia and fragile X syndrome are caused by expansion of trinucleotide repeat sequences in the deoxyribonucleic acid (DNA). These diseases show progressive severity in subsequent generations.
