Evolution and function of colour vision in mammals. The project aims to investigate colour vision in marsupials and monotremes (echidna and platypus) with differing phylogenies and biogeographic histories. Improving knowledge of the molecular structure of opsin genes mediating colour vision will be crucial to the understanding of evolution and function of this key mammalian (including human) sensory capacity.

The project aims to investigate colour vision in marsupials and monotremes (echidna and platypus) with differing phylogenies and biogeographic histories. Improving knowledge of the molecular structure of opsin genes mediating colour vision will be crucial to the understanding of evolution and function of this key mammalian (including human) sensory capacity. Understanding species colour discrimination will contribute to protective measures of Australia's unique fauna, presenting social and economic assets for the local and national community, and will set a standard that should be applied world-wide. Close international links and intellectual exchange will be invaluable to the Australian science community, including students.

Transcriptome sequencing and functional characterisation of craniate non-visual sensory systems and their adaptation to diverse light environments. Light detection (photoreception) is critical to species survival. It is not limited to vision, but also serves to set biological rhythms. In mammals, all photoreception is thought to occur solely through the eye, but in non-mammals many other tissues directly monitor light levels. However, the signalling cascades and functional roles of these non-vis ....Transcriptome sequencing and functional characterisation of craniate non-visual sensory systems and their adaptation to diverse light environments. Light detection (photoreception) is critical to species survival. It is not limited to vision, but also serves to set biological rhythms. In mammals, all photoreception is thought to occur solely through the eye, but in non-mammals many other tissues directly monitor light levels. However, the signalling cascades and functional roles of these non-visual pathways are largely unknown. This project will use high-throughput sequencing technologies and functional analyses to trace the origin and function of different irradiance detection systems in each main craniate class. By comparing species from diverse photic habitats, the influence of light as a substrate for adaptation will be investigated.Read moreRead less
Investigating the molecular mechanisms underlying non-visual photoreception and their implications in the treatment of human neurological disease. The ability of organisms to detect light is fundamental for survival and has been a major driver in evolution. The project will investigate the genetic origins of the various visual and non-visual systems and will explore its implications for the bioengineering of therapeutics for the treatment of neurological disease in humans.
