Research focuses on access to, and use of, medicines. Particular interest in how lay people understand and use medicines, and looking at particular population groups and barriers they face in accessing and using safe and appropriate medicines. I use both qualitative and quantitative research methods. Research in the Pacific and with Pacific people in New Zealand, medicines use in Tairawhiti, medications in everyday life.

Neural mechanisms underlying voluntary movements and the movement deficits of Parkinson’s disease. Motor thalamus and motor cortex function are being explored using cutting-edge optogenetic technology that enables characterisation and manipulation of part of the basal ganglia-thalamocortical pathway. Optogenetic modulation of brain activity in an animal model of Parkinson’s disease to learn how this alters motor thalamus and motor cortex activity, and behaviour.

Assoc Prof Phil Sheard
Sarcopenia, the age-related loss of muscle mass and strength that has profound implications for the elderly. He is specifically interested in the role of the motor nerve terminal because progressive withdrawal of the motor nerve from the muscle fibre seems to be a conspicuous feature of elderly muscle. He is currently examining age-related changes to the neuromuscular junction with a view to using this information to establish whether motor nerve withdrawal is a cause of muscle fibre death, or a consequence of it. Associate Professor Sheard uses electrophysiology, electron microscopy, confocal microscopy, fluorescence and transmitted light microscopy, histochemistry, immunohistochemistry, and anterograde and retrograde cell tracing techniques.
