Cellular Plasticity in the Brain: discovering molecular mechanisms controlling the production of neurons during brain development, function, ageing and disease. The program aims to understand the mechanisms regulating Brain Plasticity - this recently discovered property of the brain to respond to environmental stimuli, both physiological and pathological, by producing new functional neurons. Specifically, the program will discover how the brain's stem cells are stimulated to produce new neurons. ....Cellular Plasticity in the Brain: discovering molecular mechanisms controlling the production of neurons during brain development, function, ageing and disease. The program aims to understand the mechanisms regulating Brain Plasticity - this recently discovered property of the brain to respond to environmental stimuli, both physiological and pathological, by producing new functional neurons. Specifically, the program will discover how the brain's stem cells are stimulated to produce new neurons. This understanding will significantly expand our knowledge of how the brain develops, and how functions, like memory, are modulated by neuronal replacement. Discoveries will underpin the development of, in association with Australia's biotechnology sector, a new generation of therapeutics, which treat neurological diseases, like Stroke, by stimulating the production of functional neurons.Read moreRead less

Long-term memory systems and the human brain. Impairment of memory is a ubiquitous feature of human brain disease. A better understanding of memory processing in the brain is key to the development of better tests for the detection and monitoring of disease progression as well as the application of improved methods of rehabilitation for patients with acquired brain injury.

Molecular control of apoptosis and protein homeostasis. A million cells are produced every second by cell division. At the same time a million cells commit suicide by a process called apoptosis. When cells fail to die when they should they can develop into cancers. In heart attacks, stroke and neurodegenerative diseases, many cells appear to activate their self destruct mechanism to die unnecessarily. Drugs that can cause cancer cells to kill themselves, or drugs that prevent cells dying when th ....Molecular control of apoptosis and protein homeostasis. A million cells are produced every second by cell division. At the same time a million cells commit suicide by a process called apoptosis. When cells fail to die when they should they can develop into cancers. In heart attacks, stroke and neurodegenerative diseases, many cells appear to activate their self destruct mechanism to die unnecessarily. Drugs that can cause cancer cells to kill themselves, or drugs that prevent cells dying when they shouldn't, would make a major impact on many important diseases. Understanding the molecular mechanisms of cell death is the first step towards developing these drugs.Read moreRead less
Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between mar ....Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between marsupials and other mammals. The focus on reproduction and development will also provide invaluable knowledge to underpin efforts to conserve our endangered species and to control those that are overabundant.Read moreRead less
