My research uses EEG and MEG with children and adults to explore the neural and cognitive mechanisms of top-down attentional control. In particular, I am interested in how these control mechanisms interact with our ability to store information in working memory, and whether or not they can explain the working memory capacity differences that we observe across different individuals. One possibility is that differences in attentional control mechanisms drive these apparent memory differences.

I am particularly interested in whether this is the case in childhood. Working memory capacity variability in childhood is a strong longitudinal predictor of educational outcome; my research explores the extent to which differences in attentional control abilities across children might drive these longitudinal relationships between initial working memory capacity and subsequent academic progress.

A further possibility is that the development of these control abilities can be modified by targeted intervention, thereby improving working memory performance and educational outcome. In short, my current research seeks to understand the relationship between development, training, and the neural mechanisms of top-down attentional control. My research is supported by the British Academy, the Royal Society and the MRC.
