The first is focused on identifying, managing and mitigating fatigue in applied settings, particularly for the aviation industry. She has worked with aircraft manufacturers, national and international airlines and regulators and has conducted studies onboard aircraft and in the laboratory environment.

Leigh’s second stream of research is focused on the sleep health of women and children. She is interested in understanding the sleep of women across the perinatal period, the relationship between sleep and mental health across the lifespan, and ways we can support people to maintain good sleep health and mental health. She also has an interest in understanding inequities in sleep for women and children and the sociodemographic factors that drive these differences.
