Research
I am the Clinical Director of the NZ Brain Research Institute. I am a Neurologist, with subspecialty expertise in Movement Disorders including Parkinson’s, Huntington’s disease and botulinum toxin therapy.My research interests and expertise are:
- establishing biomarkers of cognitive decline to mild cognitive impairment (MCI) and dementia, particularly advanced MRI markers in Parkinson’s disease but also other dementias;
- eye movements in PD and other neurological disorders, in collaboration with Dr M MacAskill,
- clinical biomarkers of progression in Huntington’s disease, and
- speech and swallowing disorders in health and neurological disorders.
