Biography

I am a Research Fellow in the Physiology Department and Centre for Brain Research at the University of Auckland.

My research focusses on how brain cell activity controls behaviour and what happens when this goes awry in disease. My work utilises cellular recording in live mice (‘in vivo’) using a range of different imaging technologies. These techniques allow us to track activity in the brain in real time and relate the activity to behaviour or sensory input. To record brain cell activity, we genetically engineer brain areas of interest to make them flash when they become active. We then record movies of brain activity and synchronise them with videos of mouse behaviour or recordings of sensory stimuli presented to the animals. My current research is focused on Autism Spectrum Disorder and Alzheimer’s disease.  

I did my BSc (Biomedical Science), Honours and PhD at the University of Auckland then moved to Amsterdam for 6 years as a Postdoctoral Fellow. In 2016 I returned to the University of Auckland on a Neurological Foundation Repatriation Fellowship. This Fellowship was co-funded with an Auckland Medical Research Foundation Project grant and allowed me to establish in vivo imaging in Auckland. Together with a Marsden Fast-Start this funding has enabled my team to investigate development and function of the auditory and prefrontal cortex in a mouse model of Autism Spectrum Disorder. In 2018 I obtained equipment funding from Maurice Paykel Trust and Lottery Health Research to customise a two-photon microscope for in vivo brain imaging. With funding from the Faculty of Science Research Development Fund and a Neurological Foundation Project Grant we are now applying this technology to better understand cellular activity in the auditory cortex in Autism Spectrum Disorder. We have recently established minaturised microscopes ('miniscope') recordings in the lab with funding from Neurological Foundation Small Project Grant and Brain Research New Zealand.
