A/Professor Paul Lockhart
Biography:
Associate Professor Paul Lockhart is the Group Leader of Neurogenetic Research at the Murdoch Childrens Research Institute.
He is currently the National Health and Medical Research Council (NHMRC) Career Development Fellow and leads a research group that investigates the molecular basis of neurogenetic disorders.
Paul received his PhD in Genetics (Title: Molecular analysis of copper transport in sheep) from the University of Melbourne in 2000. He was awarded a NHMRC CJ Martin Fellowship to study the genetics of neurodegenerative disorders, specifically Parkinson's disease, with Professor John Hardy (2000-2001) and Professor Matthew Farrer (2002-2003) at The Mayo Clinic, Florida. He returned to Australia in 2004 and joined the newly formed Bruce Lefroy Centre (BLC) at Murdoch Childrens, with the aim of establishing a laboratory research group to complement the clinical and public health research activities of the BLC. He received a NHMRC RD Wright Fellowship in 2005 and was appointed Co-Director of the BLC in 2009.

Research:
The identification and characterisation of genes underlying Mendelian disorders has been responsible for the rapid advances in our understanding of human disease over the last 20 years, and has considerable impact on our understanding of complex common diseases that are currently considered to be idiopathic.
Recent advances in genetic technologies mean we now have the ability to sequence entire exomes and genomes in a rapid and cost effective manner. This means gene discovery can now be effectively performed in families with few affected individuals and sib-pairs, both previously underpowered for such analysis. Indeed, we are rapidly approaching the point where whole exome/genome sequencing of individuals will be a cost-effective method for diagnosis of many disorders. These genome sequence datasets have enormous potential for application in the rapidly developing field of personalised medicine. These advances have particular relevance to disorders of the brain, which is a specific area of research interest.
In Australia, brain and mind disorders collectively are one of the largest and fastest growing disease burdens. Affecting both the young and the elderly, these disorders are typically chronic and debilitating with a large economic cost to individuals and the community. A current focus of the laboratory is to apply new genomic technologies and capacity to neurogenetic disorders that have previously proven intractable to genetic analysis. The laboratory works very closely with the clinical services of Genetic Health Services Victoria and the Royal Children's Hospital. Once novel disease-associated genes are identified, we perform molecular studies in cell and animal models to determine the function of the encoded protein and investigate the underlying pathogenesis of disease. In addition to the immediate counselling and clinical benefit to affected patients and families, this research is essential for the development of treatment programs and prevention or onset-delay strategies for brain and mind disorders.
