Research summary
Movement Disorders and Brain Research

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.
I regularly conduct clinical pharmaceutical trials in Parkinson’s and other neurological disorders This has enabled patients not only to have early access to new treatments but also and regular clinical review and oversight.
