The major research interests of my group is focused on the key neurological disorders of Alzheimer's Disease, Parkinson's Disease, Motor Neuron Disease, Stroke and Traumatic Brain Injury. The group is studying the key proteins associated with these diseases with a major focus on the Amyloid Precursor Protein (APP) family, Amyloid-beta peptide and alpha-synuclein. We want to identify the critical molecular interactions and cellular pathways that cause the neuronal dysfunction / death that underpin these diseases, and to develop therapeutic approaches based on targeting these proteins and pathways. We have a strong interest in metallobiology, protein aggregation, protein-protein interactions, protein structure, neuroprotection, neuronal differentiation and neurodegeneration.
The lab utilises molecular biology, cell biology (primary cells and immortalized cell lines), animal models of disease, recombinant protein expression and purification, gene expression analysis and protein chemistry.
- To determine the function of the Amyloid Precursor Protein family in modulating traumatic brain injury and motor neurone disease
- To determine the key molecular interactions and cellular pathways that are critical for modulating protein aggregation and neurotoxicity in Alzheimer's and Parkinson's disease.
- Identifying APP as a neuroprotective modulator of traumatic brain injury
- Solving the structure of key domains of the APP-family.
- Identifying APP as a modulator of metal homeostasis.
- Identifying dopamine as a modulator of α-synuclein aggregation.
