My main research interest is the understanding of sleep: what factors affect sleep; how sleep affects subjective state, behaviour and physiology; and what mechanisms underly sleep. This has led to my involvement in studies of: the effects of drugs and alcohol on sleep; sleep deprivation; displacement of the sleep period; sleep and depression; aging and sleep; and the relationship between the menstrual cycle and sleep. I have also been involved in the clinical assessment and treatment of sleep disorders. The principal focus of my present research is the understanding of how sleep loss and sleepiness affects skilled performance such as driving. Our current investigations are using a small driving simulator and subjective, behavioural and physiological assessments of sleepiness to gain a greater theoretical understanding of the relationship between sleepiness and performance which we hope will lead to improvements in our capacity to predict and detect deterioration under real-life conditions.
