Research interests

I work at the interface betweenneuropathological(human tissue) research and quantitative neurochemistry, using these skills to investigate disease mechanisms in Parkinson’s disease. This human-based approach for identifying disease mechanisms is critically important in this disorder, as unlike some other neurodegenerative diseases, Parkinson’s disease only occurs in the human. Funded by an international Research Fellowship (Alexander von Humboldt Foundation, Germany) and then consecutive federal Australian Research Fellowships and federal grant funding, I demonstrated that neuromelanin, the pigment which characterises the vulnerable cells in the Parkinson’s disease brain, plays an active neuroprotective role in healthy dopaminergic cells. This changed the then dogma that neuromelanin pigment has a negative impact upon the healthy brain. I then demonstrated abnormal changes in neuromelanin, and associated cellular metals, reflecting the pattern of brain cell death in Parkinson’s disease, indicating that changes in this metal-binding molecule may play a role in the etiology of Parkinson’s disease. This prompted me to investigate other metal-binding proteins in Parkinson’s disease and led to the discovery of SOD1 proteinopathy associated with neuronal death in Parkinson’s disease brain, and the similarities between this pathology and the well-documented SOD1 proteinopathy present in post mortem spinal cord from patients with familial amyotrophic lateral sclerosis.
