Research Interests

My research interests center around sleep, fatigue, performance, countermeasures, and safety in shiftwork. I have worked directly with safety-critical industries such as aviation, petrochemical and road transport to better understand and manage the risk of fatigue in these operations. For me, working with industry highlighted the need for academic research with a practical focus. It is this focus that drives my current research interests and endeavours. My PhD thesis explored the impact of sleep inertia in shift work contexts including split duty schedules and napping on night shifts. I am currently investigating the influence of irregular sleep-wake schedules on circadian rhythms, performance, learning, and mood.
I am passionate about translating and communicating laboratory findings to real-world environments and non-academic audiences. Through my work, I hope to develop evidence-based guidance to improve public health, performance, and safety.
