I study higher-level cognition and its development across the lifespan. I am particularly interested in understanding what limits memory for the immediate past, and how those limits change as people grow older. My research has a strong translational perspective that uses core principles of developmental and cognitive psychology to understand classroom learning. I am currently undertaking a programme of research to probe mind wandering in children, examine its phenomenology, and consider the costs and benefits that this experience can bring in the context of educational attainment.
