I am a Neurologist and Cognitive Neuroscientist with a strong interest in cognitive disorders and the normal neural processes that underlie these deficits. My recent research has focussed on understanding the mechanisms that underlie apathy – a disorder of motivation with often debilitating consequences – in various neurological disorders including Parkinson’s disease, cerebral small vessel disease and Huntington’s disease. I use specifically designed behavioural paradigms, physiological recordings (e.g. of pupillary responses to reward) and imaging techniques (including fMRI, diffusion imaging and arterial spin labelling) to investigate whether apathy is caused by disruption of normal decision making processes – particularly the integration of reward information and action costs to drive choice. My work is heavily influenced by basic neuroscience developments, which I aim to translate to the clinical context. In turn, by studying patients with disorders of cognition I also aim to improve understanding of these underlying normal processes.
 
Following completion of Neurology specialist training in 2014 I undertook a DPhil at the University of Oxford in Professor Masud Husain’s cognitive neurology research group. I have now returned to New Zealand where I work as a Neurologist specialising in Cognitive and Movement disorders, and am developing a research program centred on understanding neurobehavioural disorders and the complex neural interplay between cortical and subcortical regions that leads to the generation (or not) of actions.

October 2019: I have a Post-doctoral position available!

I have funding to employ a post-doctoral researcher full-time for one year beginning early 2020, to investigate patient trajectories and antecedent causes of apathy in people with Parkinson’s disease. The project is based at the NZBRI, where a longitudinal cohort of Parkinson’s patients has been followed since 2007, including extensive imaging, neuropsychology and clinical measures. Data is already collected, and the role will predominantly involve leading the analysis and interpretation of results.
