After obtaining a BSc in Biomedical Engineering at the University of Ulster, Maurice completed a PhD in electrophysiology of retinal arteriolar myocytes and retinal blood flow regulation at the Queen’s University of Belfast in Northern Ireland. Following this, he obtained a Post-Doctoral research position studying TRP channel characteristics using the patch clamp method at the LCMS in the Queen’s Medical Center in Honolulu and University of Hawai’i at Manoa. Currently, Maurice is using the Dynamic patch clamping technique and calcium fluorescence imaging to study electrical cellular behaviour and interaction in cortex and striatum brain slices.

He is also using optogenetics to investigate pattern formation in the somatosensory cortex and the role of dopamine in reward reinforcement. Maurice is currently co-supervised by Dr. Bruce McNaughton and Dr. Aaron Gruber.
