Pattern recognition in animals and machines: using machine learning to reveal cues central to the identification of individuals. The power to recognise individuals of a species requires significant image and pattern discrimination abilities. Yet, individual recognition has been found in a huge range of species, from humans to invertebrates demonstrating its importance for social interactions. The project will investigate this ability in lower vertebrates (fish, with no visual cortex), so as to u ....Pattern recognition in animals and machines: using machine learning to reveal cues central to the identification of individuals. The power to recognise individuals of a species requires significant image and pattern discrimination abilities. Yet, individual recognition has been found in a huge range of species, from humans to invertebrates demonstrating its importance for social interactions. The project will investigate this ability in lower vertebrates (fish, with no visual cortex), so as to understand the underlying mechanisms of pattern discrimination. The project will also test how robust this ability is during changes in water quality (elevated carbon dioxide levels and increased turbidity). The outcomes will further our knowledge base in lower vertebrate vision and evolution, and also have implications for human vision, image analysis, and artificial vision.Read moreRead less
Melanopsin function in humans. This project aims to understand melanopsin signalling in humans. A newly discovered retinal ganglion cell class expresses the melanopsin photopigment. Melanopsin signalling controls neural functions for light dependent image formation and non-image forming processes. Many of these are unknown in humans. This project will use a 5-primary photostimulator to define how melanopsin controls these processes in humans. The outcomes are expected to advance understanding of ....Melanopsin function in humans.

This project will use a 5-primary photostimulator to define how melanopsin controls these processes in humans. The outcomes are expected to advance understanding of human vision. This could provide avenues for using light to increase active participation in society and improve health and well-being, and strategies to assess human vision and the body’s internal clock.Read moreRead less
The Helmsman Project: Giving at-risk adolescents skills to navigate life’s journey and make a difference. This project aims to investigate how to keep able but disadvantaged youth engaged in school and give them the psychological tools they need to succeed. To meet this challenge, this project aims to propose a randomised control and extended baseline control test of a combined personal coaching and outdoor education (sailing experience) program designed to foster positive psychological outcomes ....The Helmsman Project: Giving at-risk adolescents skills to navigate life’s journey and make a difference. This project aims to investigate how to keep able but disadvantaged youth engaged in school and give them the psychological tools they need to succeed. To meet this challenge, this project aims to propose a randomised control and extended baseline control test of a combined personal coaching and outdoor education (sailing experience) program designed to foster positive psychological outcomes by developing goal strategies, hope, resilience, and self-regulation. The study aims to be extensive and novel, capturing the experiences of not just the participants but their peers, parents, teachers, and alumni mentors of the program. Both traditional survey and experience sampling data will be collected.Read moreRead less

Summary
Investigating the evolution of human traits and the maintenance of heritable individual differences. This project will use twin studies, statistical genetics, and experimental methods to investigate genetic and environmental influences on evolutionarily relevant human traits. This will help reveal how human traits evolved and why all individuals are genetically different despite Darwinian selection favouring only the most advantageous genes.
The rules governing combined rod and cone photoreceptor signalling in visual pathways. The research program investigates vision at dim (mesopic) light levels where rod and cone photoreceptors simultaneously transmit visual information. The interaction between rod and cone signals is not trivial because their different amplitudes, timings and delays significantly change the perceptual qualities of our visual experience. The research addresses fundamental questions about how the retina and brain i ....The rules governing combined rod and cone photoreceptor signalling in visual pathways. The research program investigates vision at dim (mesopic) light levels where rod and cone photoreceptors simultaneously transmit visual information. The interaction between rod and cone signals is not trivial because their different amplitudes, timings and delays significantly change the perceptual qualities of our visual experience. The research addresses fundamental questions about how the retina and brain integrate disparate signals from the rods and cones to produce a homogenous visual percept. New psychophysical and electroretinographic paradigms will independently control the retinal photoreceptors to resolve the long standing problem of how noise modifies signalling and information flow between the retina and visual cortex.Read moreRead less
Multimodal testing for a fast subcortical route for salient visual stimuli. This project aims to uncover links between underlying brain circuitry, uncertainty and consciousness, and perceptions of fear. The project will use a multi-modal combination of brain imaging and neural recording techniques to generate new knowledge about the brain’s processing of biologically relevant information. The expected outcomes will enhance our knowledge of how the brain rapidly and non-consciously prepares the ....Multimodal testing for a fast subcortical route for salient visual stimuli. This project aims to uncover links between underlying brain circuitry, uncertainty and consciousness, and perceptions of fear. The project will use a multi-modal combination of brain imaging and neural recording techniques to generate new knowledge about the brain’s processing of biologically relevant information. The expected outcomes will enhance our knowledge of how the brain rapidly and non-consciously prepares the body for potential escape behaviours and of the brain pathways engaged in fear perception. The outcomes have the potential to inform strategies for overcoming anxiety and its effects on daily life, social interactions and workplace productivity.Read moreRead less

Treatment-induced compulsive behaviours: Ethical and policy implications. Compulsive behaviours represent one of the largest preventable burdens in society. Some medications, such as those used to treat Parkinson's disease, can produce severe compulsions in certain individuals, which are akin to addiction.

Compulsive behaviours represent one of the largest preventable burdens in society. Some medications, such as those used to treat Parkinson's disease, can produce severe compulsions in certain individuals, which are akin to addiction. This project will explore: neurocognitive changes caused by these medications; the impact that drug-induced compulsive behaviours have on affected individuals, their sense of agency, identity and moral responsibility; and the ethical, legal and policy consequences of drug-induced behaviour. This project will help us to understand the neuropsychology of compulsive behaviour and reduce its occurrence. It will also enable society to meet the ethical and policy challenges raised by neuroscience research on compulsive behaviour.Read moreRead less
