Professor Jun Au


Dr. Au obtained his PhD degree in the Department of Paediatrics, CUHK. His research has centered around obstructive sleep apnea (OSA) and sleep deprivation. Particularly, he has been investigating the cardiovascular complications and the treatment responses, the natural history of OSA from childhood to adulthood, the familial aggregation and heritability of childhood OSA, the diagnosis of OSA, and the epidemiology of OSA in different pediatric age groups. Besides, he has been a registered polysomnographic technologist (RPSGT) since 2008 and runs a regular training course for respiratory and sleep medicine trainees and research personnel involved in the management of paediatric sleep problems. He is currently the person-in-charge of the sleep diagnostic and research laboratory in the Department of Paediatrics, Prince of Wales Hospital. He has been frequently invited to lecture and provide educational workshops in a variety of sleep conferences both locally and in mainland China.
