Much of my research has focused on the development of different aspects of temporal cognition in young children. I am interested in children's thinking and reasoning about time, and how this affects their decision making. My research on children's decision making, conducted with Cristina Atance, Patrick Burns, Aidan Feeney, and Sarah Beck, has focused on intertemporal choice as well as the role of regret in children's decisions. Research on mathematical cognition with Kinga Morsanyi and Patrick O'Connor has examined how representing and processing temporal order information may be important in the development of maths skills. 

I have an established interest in interdisciplinary research with philosophy, and have worked with Christoph Hoerl on a variety of interdisciplinary topics including time, memory, and counterfactuals. 

I teach developmental psychology primarily at MSc level.

I completed my undergraduate degree and PhD at the Department of Experimental Psychology, University of Cambridge. After a year lecturing at the University of Kent, I moved to the University of Warwick to work as a postdoctoral researcher with Gordon Brown. In 2000, I was appointed as a lecturer at Warwick, before moving to Queen's University Belfast in 2002. I was promoted to Reader and then to Professor of Cognitive Development in 2010.
