Biography
Dr Melinda Fitzgerald has been awarded an NHMRC Career Development Fellowship and is Associate Professor at Experimental and Regenerative Neurosciences, School of Animal Biology, The University of Western Australia. She is an independent researcher conceiving and conducting original research, designing and assessing clinically relevant strategies for treatment of neurotrauma. She leads a team of 12 researchers and post-graduate students.
Key research
A/Prof Fitzgerald’s research is focused around understanding and preventing the loss of function that occurs following neurotrauma. She uses innovative analytical techniques to demonstrate changes to key biochemical, cellular and structural components of nerves following injury and is assessing treatment strategies including nanotechnologies and combinatorial pharmacotherapeutics. Her drive to translate her research findings to the clinic is evidenced by her current collaborative clinical trial assessing biomarkers and MRI for prediction of post-concussion syndrome.

Roles, responsibilities and expertise
In her 13 post-doctoral years A/Prof Fitzgerald has published 66 papers (45 in the last 5 FTE years), of which she is first author on 16 and last author on 27. Many of her recent papers have been published in influential, international journals, including ACS Nano (exceptional, IF=10.5), Small (IF=7.8, multi-disciplinary), IOVS (premier Ophthalmology journal), Neuropharmacology, J Neurotrauma (highly influential). The quality and impact of A/Prof Fitzgerald’s research and her growing leadership in the field is evidenced by numerous invitations to speak at local, national (10) and international (15) conferences from 2010-2015/6, including keynote and Symposium presentations. She is a Handling Editor for the Journal of Neurochemistry, the Australian representative for the Asia Pacific Regional Committee for IBRO, serves on the international scientific committees for BIOMATSEN2016 and ICNT2016, is an Editorial Board Member for Neural Regeneration Research, Frontiers Journals and an Associate editor for PeerJ. Currently Held Grants/Projects total $2 million; she is CIA for all of these; total funding awarded for her career is $6.5 million, $3.9 million as CIA. A/Prof Fitzgerald currently holds an NMHRC Career Development Fellowship, two CIA Project Grants and was sole CI on an NHMRC ECR Project grant. A patent entitled ‘Multifunctional Nanoparticles’ reached international PCT stage and was developed by a biotechnology company. In the past 5 years A/Prof Fitzgerald has supervised 20 Honours students or equivalent, 10 PhD students (5 completions), 6 post-doctoral researchers and gives regular guest lectures.

A/Prof Fitzgerald’s commitment to discipline is evidenced by her roles as Chairperson and Convener of the annual Symposium of Western Australian Neuroscience (SWAN), and the UWA neuroscience seminar series. She is Co-Chair of her departmental Research Committee, a member of the UWA Faculty of Science Planning Task Force addressing Grantsmanship, Mentoring and Expectations, and is spearheading a drive to disseminate collated information regarding all seminars in science and health in Perth. A/Prof Fitzgerald reviews for numerous scientific journals including EJN, IOVS, Neurochem. Int., international funding bodies including fight for Sight UK, MS Australia and the Alzheimer’s Australia Dementia Research Foundation and serves on NHMRC and MS Australia Grant Review Panels. In addition, A/Prof Fitzgerald has been selected to participate in Homeward Bound, an international leadership and strategy program for women scientists, run as an expedition to Antarctica, designed to increase the proportion of women in the higher levels of science. As a consequence A/Prof Fitzgerald has instituted a UWA Faculty of Science gender equity group and coordinates the UWA Faculty of Science mentoring program for PhD students and early career researchers, currently being expanded across Institutional boundaries. She is a member of the Perkins Institute EMCR Mentoring Committee and regularly speaks at institutional, scientific and community events regarding gender equity in science.
Future research
Using her model of secondary degeneration A/Prof Fitzgerald has demonstrated that combinations of calcium channel inhibitors prevent the loosening of myelin lamellae and decompaction that occurs as a consequence of secondary degeneration. Furthermore, combinatorial therapy prevented lengthening of the node of Ranvier and preserved function. She is working towards optimisation of this clinically relevant strategy. A/Prof Fitzgerald is also part of a highly productive collaboration to generate nanotechnologies for delivery of calcium channel blockers and anti-oxidants to limit secondary degeneration following partial injury to the CNS (Centre for Strategic Nanofabrication, UWA).
The goal of the research team is to develop a suite of prognostic indicators to predict post concussion syndrome following mild traumatic brain injury, and in so doing identify a cohort of patients suitable for treatment using the therapeutic strategies the team has developed.

Following injury to the central nervous system, functional loss is exacerbated by spreading damage causing secondary degeneration of surrounding tissue. Using a model of secondary degeneration where the optic nerve is partially transected, Dr Fitzgerald and her team have demonstrated changes in calcium distributions, oxidative stress and myelin abnormalities in nerve vulnerable to spreading damage. These biochemical and structural changes were associated with loss of visual function. Therapeutic strategies designed to reduce oxidative stress and dysmyelination, including combination of calcium channel inhibitors and red/ near-infrared irradiation therapy, prevent the functional loss of secondary degeneration in this model (1-5).
Core capabilities
Our key area of expertise is our animal model of secondary degeneration, allowing spatial separation of the primary injury from the area of nerve vulnerable to spreading damage. The model features excellent reproducibility, allowing functional outcomes to be assessed with high chances of statistically significant results.
Outcome measures include neuroprotection, assessments of multiple cell populations including inflammatory cell infiltration, oxidative stress, myelin structure (electron microscopy), and behavioural assessments of visual function.
•The model is relevant for assessments of efficacy of pharmaceuticals, alternative medicine or medical devices designed to prevent secondary degeneration following neurotrauma.
•The model is also relevant for assessment of therapeutic strategies for normotensive glaucoma and traumatic optic neuropathy.
Additional capabilities and techniques in routine use
Electron microscopy, fluorescence microscopy, immunohistochemistry including extensive image analysis capability, nanoscale secondary ion mass spectroscopy, animal surgery, cell culture including organotypic spinal cord and brain slice cultures, cell fate mapping, enzyme assays, histochemical assessments.
Assessment of multiple indicators of oxidative stress in cultured cells and in animal tissue, including: reactive species, antioxidant enzymes (manganese superoxide dismutase, glutathione peroxidase, heme oxygenase), indicators of oxidative damage to DNA lipids and proteins within specific cell types. We also conduct assessment of changes in calcium concentrations in cultured cells.

Current projects
Together with her team, Dr Fitzgerald is currently exploring the mechanisms by which secondary degeneration spreads as well as potential therapeutic strategies for treatment, including remyelination therapies, near infra red light and nanotechnologies for targeted delivery.
She has recently commenced a clinical trial aiming to identify predictors of poor outcome following concussion and has identified novel indicators of damage in more severe traumatic brain injury and models of concussion.
