Overview

Background

My research focuses on understanding the dynamics of decision-making, motivation, fatigue, and stress and how these processes affect our performance and mental health. I use computational and mathematical models to understand how these complex processes evolve and interact over time. I use this knowledge to help design work environments that promote happier, healthier, and more effective work. Practical applications of this work so far have included providing evidence-based recommendations regarding alternative work concepts such as the four-day work week, enhancing the capacity and safety of unmanned aerial systems operations, facilitating tactical decision-making in military contexts, providing tools to forecast fatigue in submarine operations, and improving climate change communication practices. My work has been published in premier journals such as Psychological Review, Psychological Science, Journal of Applied Psychology, The Leadership Quarterly, Annual Review of Organizational Psychology and Organizational Behavior, Organizational Research Methods, Journal of Neuroscience, and Global Environmental Change. My research has attracted more than $2 million in external funding, which has included over $1 million from the Australian Research Council and over $1 million of industry funding. The success of my research program has been recognised by an ARC DECRA Fellowship and Early Career Researcher Awards from the Australian Psychological Society, the Australasian Mathematical Psychology Society, and the Faculty of Health and Behavioural Sciences at UQ.
