This is an application for reappointment as a Principal Research Fellow. My primary area of research is preclinical studies of addiction, with a particular emphasis on relapse. I am increasingly engaged in translational studies.
Social Dysfunction After Paediatric Brain Injury In Mice

Summary
Brain injuries during early childhood may evolve over time, with long-lasting consequences on one's ability to socially interact with others. In this study, we hypothesise that social behaviour problems result from damage to white matter tracts in the immature brain. By using a unique model of brain injury in young mice, plus advanced imaging and behavioural methods, we will provide new understanding about the cause of social problems, and evaluate a rehabilitation approach to improve outcomes.
Early life overfeeding - mechanisms for programming obesity and long-term immune dysfunction. Early life overfeeding can lead to obesity and related changes in adulthood. With this study we will discover how overfeeding can permanently alter an animal's development so that its body weight and immune functions are dysregulated. The outcomes will facilitate appropriate design of animal experiments considering the impact of neonatal programming. They will also contribute to more efficient feeding p ....Early life overfeeding - mechanisms for programming obesity and long-term immune dysfunction. Early life overfeeding can lead to obesity and related changes in adulthood. With this study we will discover how overfeeding can permanently alter an animal's development so that its body weight and immune functions are dysregulated. The outcomes will facilitate appropriate design of animal experiments considering the impact of neonatal programming. They will also contribute to more efficient feeding protocols for meat production in agriculture and identify targets for risk management and for preventing and ameliorating early life overfeeding effects in humans. This investigation therefore has clear benefits to the social, economic, and health aspects of obesity and to basic science and agriculture.Read moreRead less
Translating Epilepsy Research Into Clinical Practice

Summary
We aim to turn laboratory science into real improvements in the health of people with epilepsy. Firstly, a rise in the acidity of the blood from breathing less and a rise in carbon dioxide, may contribute to seizures finishing. We aim to develop a safe, rapid, non-sedating way to treat seizures using a small amount of carbon dioxide in oxygen. Secondly, inherited problems with transporting sugar from the blood to the brain are increasingly recognised as a cause of epilepsy. We will develop a nat ....We aim to turn laboratory science into real improvements in the health of people with epilepsy.

Human Epilepsy: Understanding Biology To Improve Outcomes

Funding Amount
$16,657,948.00
Summary
Our team of neurologists, molecular geneticists, physiologists and brain imaging specialists and leads the world in the discovery of the genetic causes of epilepsy. Through this work we will identify genes underlying epilepsy and study how genetic variations result in the development of seizures. Advanced brain imaging will be used to understand the effects of genetic variation on brain structure and function. This study may lead to new diagnostic methods and treatments for epilepsy.
A New Animal Model Of The Prodrome In Schizophrenia. Enhanced Dopamine In Prodromal Schizophrenia (EDiPs)

Funding Amount
$571,990.00
Summary
Psychiatrists now recognize a pre-symptomatic stage is present in people at risk of developing schizophrenia. Using new brain imaging techniques we now know that some of these individuals have changes in a major neurotransmitter, dopamine, prior to being diagnosed. We have developed a new model in animals, which recreates these exact same changes at a comparable age. We want to now understand what are the broader effects in the brain and try and block these changes in dopamine with new drugs.
A Potential Analgesic Target In A Novel Clinically-relevant Neuropathic Pain Pathway.

Funding Amount
$685,811.00
Summary
Persistent pain arising from tissue damage, to nerves, muscles or joints for example, is devastating for patients and a huge social and economic burden. This work will investigate one of the pathways that goes awry after sensory nerves are damaged. These experiments will also test whether a drug being developed to treat Alzheimer's disease is effective at blocking the persistent nerve hypersensitivity that sometimes develops after injury.
Muscling in on the brain. This project investigates an enzyme that 'matures' neurotransmitters in the brain that regulate food intake, energy expenditure and blood pressure by the brain; these neurotransmitters arise from the same precursor molecule. This project will show the physiological relevance of this enzyme in obesity.
Neuroprotection Against Parkinson’s Disease With Remote Photobiomodulation
Funder

Funding Amount
$314,818.00
Summary
Treating the head of rodents with low-intensity 670nm light protects against Parkinson’s disease (PD), but the large size of the human skull and brain precludes clinical translation of this treatment. We have discovered that the brain is also protected when light is targeted at peripheral tissues (e.g. a limb), overcoming problems of delivery. This project aims to optimise this treatment and better understand how it works, to lay the scientific basis for a clinical trial.
This Project will produce the first map of the brain mechanisms that motivate unhealthy food choices in obesity. This outcome can inform the development of novel treatment approaches for obesity that modify the preference for high-calorie, unhealthy foods by changing the neural bases of such preferences.
