How does my research help children?

Numerical and mathematical skills are of fundamental importance to a successful career and a health life.  Indeed low numeracy skills have not only been associated with poorer educational progress and career trajectories but are also linked to increased rates of unemployment, physical illness, clinical depression, and even incarceratino.  My team and I conduct research to better understand the origins of numerical and mathematical difficulties in young children in order to find better ways to identify children who struggle with even the most basic numerical and mathematical competence and to find ways to intervene early to prevent the long term negative consequences of poor numeracy skills.

Research

Research

Research focuses on gaining a better understanding of how children develop numerical and mathematical competencies, why some children fail to acquire basic calculation skills (Developmental Dyscalculia) as well as what brain circuits are associated with the processing of number and our ability to calculate.  One of the central aims of our research is to better understand how basic numerical competencies, those that humans share with other species, become transformed through the processes of development and enculturation.  Myself and my team use non-invasive neuroimaging technologies such as fMRI, DTI and ERPs as well as traditional behavioral methods to explore these questions.

I am Interested in forging greater links between neuroscience and education, as part of the emerging field of 'Mind, Brain and Education' or 'Educational Neuroscience' and therefore in using insights from the study of neurocognitive mechanisms to inform educational practice and policy.
