Biography

I completed my undergraduate studies in Neuroscience and English Literature at the University of Otago, and graduated with a PhD from the Department of Anatomy, in Dr. Joanna Williams' lab. My PhD research project was entitled, ‘MicroRNA regulation in dentate gyrus subregions following induction of long-term potentiation in vivo’. It involved characterising changes in gene expression after the induction of long-term potentiation in awake rats. The main objective was to understand how microRNAs contribute to the maintenance of long-term potentiation, a model of memory.

I have a strong interest in science communication and I'm committed to public engagement with biomedical research.

Research | Current

I am a BRNZ Post-Doctoral Research Fellow working in the Human Brain Plasticity and Neurodegenerative Diseases Research Group, led by AP Maurice Curtis.

My current research is focused on identifying early biomarkers of frontotemporal dementia, a neurodegenerative disease that profoundly affects language, behaviour, and cognition. This research involves searching for dysregulated plasma microRNAs in people who carry a genetic mutation that will cause frontotemporal dementia in the future. Our hope is that we will be able to identify a 'signature' of microRNA changes that indicates very early disease, so that we can intervene at this early stage to prevent or slow down the disease process. We are also investigating other potential early biomarkers, including olfaction deficits and neuropsychological impairment.
