Research Overview

The John Trinder Sleep Laboratory conducts a variety of sleep related research including the effects of poor sleep on mental health and cognition, as well as research to better understand the causes for sleep disorders such as obstructive sleep apnea.

• Respiratory and cardiovascular aspects of sleep in the context of Obstructive Sleep Apnoea (including role of lung volume, arousal from sleep, OSA in Quadriplegia, treatment using acupuncture and surgical weight loss, and upper airway physiology).
• The effects of alcohol on sleep and memory in adolescence
• Sleep related control of the upper airway muscles
• Fatigue/sleepiness in airline cabin crew
• Sleep and Mental Health
• Sleep and addiction
• Sleep disruption and negative memory bias

About Emeritus Professor John Trinder

Professor Emeritus John Trinder established the Sleep Laboratory in 1987 and directed it until his retirement in 2015. Professor Trinder’s research work dramatically advanced the field of sleep medicine. During his career, he has published more than 200 scholarly articles on various aspects of sleep.

In 2012, he was awarded the Australasian Sleep Associations Distinguished Achievement Award for his exceptional achievements in the fields of sleep health and sleep science. The fact that he had continuous funding from the NHMRC and ARC for 20 years prior to his retirement was a remarkable recognition of his research prowess.

Professor Trinder has also served as President of the Australasian Sleep Association and was Editor in Chief of two prestigious sleep journals; Sleep, and the Journal of Sleep Research.
