Research
As MRI Research Manager at the NZ Brain Research Institute, I oversee all imaging at the NZBRI. This provides me with the opportunity to become involved in a wide range of neurological research, including child development, mild traumatic brain injury, post-traumatic stress disorder, neurodegenerative diseases, and more.
As an Associate Professor in the Department of Medicine, my primary focus is on the development and application of Magnetic Resonance Imaging (MRI) techniques to advance our understanding of cognitive decline in Parkinson’s disease.
