Gary Egan is a Principal Research Fellow at the Howard Florey Institute, University of Melbourne and Head of the Neuroimaging and Neuroinformatics Laboratory in the Centre for Neuroscience, University of Melbourne. He completed a PhD at the University of Melbourne (1989) and a post-doctoral fellowship at the European Centre for Particle Physics research (CERN), Geneva in the field of particle physics. In 1990 he was appointed Senior Scientist to establish the Positron Emission Tomography (PET) Centre, Austin Hospital, Melbourne, and initiated and led the brain mapping research program based on PET activation studies and other quantitative measures of brain function.
In 1998 he joined the Howard Florey Institute to establish a small animal magnetic resonance imaging (MRI) and spectroscopy facility. As Head of the Neuroimaging Group at the Howard Florey Institute, Prof Egan leads a multi-disciplinary team of 25 researchers and students undertaking MR imaging research.
Research Interests
Currently, Prof Egan’s research is focused on development of novel neuroimaging data analysis and modelling methods, creation and management of neuroimaging databases (neuroinformatics), and on neuroimaging research in humans and small animals. The main biomedical research programs within the group are MR imaging of small animal models of human diseases including multiple sclerosis, Huntington’s disease and epilepsy, and human imaging studies in these diseases.
Prof Egan is currently developing a $1 million ARC-funded computing facility for online storage of large MR image sets, involving multiple nodes at the University of Melbourne (primary) and the University of Queensland (secondary) and the University of NSW (secondary). Currently, in collaboration with Silicon Graphics Inc, Prof Egan and colleagues are developing software tools for the archiving, retrieval and analysis of MR images.
Since joining the Howard Florey Institute, Prof Egan has developed local human MRI research collaborations with the Royal Children’s Hospital, the Brain Research Institute, and the Mental Health Research Institute. International brain imaging research programs have been established in collaboration with the Research Imaging Centre, San Antonio, Texas involving neuroimaging studies of human physiology, with the Functional Imaging Centre, Georgetown University, Washington D.C. involving neuroimaging studies of human autonomic function, involving neuroimaging studies of auditory hallucinations in schizophrenia.
Laboratory Techniques
- Magnetic Resonance Imaging (MRI)
- Functional Magnetic Resonance Imaging (fMRI)
- Diffusion Tensor Imaging (DTI)
- Contrast agent-enhanced MRI, including Manganese-enhanced MRI (MEMRI)
Additional Information
Recently, expansion of a small animal high field imaging facility has been possible as part of the National Imaging Facility (NIF) funded by the National Collaborative Research Infrastructure Strategy (NCRIS). The facility will provide researchers with access to the infrastructure and networks necessary to undertake world-class imaging research. Another step toward enhancing Australian neuroinformatics research has been made through establishment of a Planning Committee for Australian membership of the International Neuroinformatics Coordinating Facility (INCF), an international organisation founded in 2005 to enhance international neuroscience research collaboration, on the recommendations of the OECD Working Group on Neuroinformatics.
