School of Health Sciences

Dr. Chan is a lecturer at the University of New South Wales and a conjoint research fellow at Neuroscience Research Australia. He holds a Doctor of Philosophy degree from UNSW, a Master's in Epidemiology and Biostatistics with Salutatorian honours from CUHK, and a Bachelor's degree in Physiotherapy with honours from PolyU. In addition to his academic work, Lloyd has extensive experience as a physiotherapist, providing care to people with Parkinson's disease and stroke survivors in acute hospitals, rehabilitation centres, and outreach settings.

His studies revolve around two themes: quantifying daily-life walking speed/quality and predicting disease using smartwatches. The resultant innovations have been adopted by fellow researchers and translated into actual clinical practices. Currently, he is working on sensor-based gait abnormality detection in various clinical populations, including people with Parkinson's disease and those with proximal femoral fractures.
