Professional Summary

Dr. Daniel Ansari is a Professor and Canada Research Chair in Developmental Cognitive Neuroscience in the Department of Psychology at the Western University Ontario, where he heads the Numerical Cognition Laboratory.

Dr. Ansari and his team explore the developmental pathways underlying both the typical and atypical development of mathematical skills using both behavioural and neuroimaging methods, . The 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.

Dr Ansari received his bachelor's degree in Psychology from the University of Sussex at Brighton, an MSc in Neuroscience from the University of Oxford and his PhD from University College London. He has also received several prestigious awards including the ‘Early Career Contributions’ Award from the Society for Research in Child Development (2009), the Boyd McCandless Early Researcher Award from the American Psychological Association (2011).In 2014, Dr. Ansari was named as a member of the inaugural cohort of the College of New Scholars, Artists and Scientists of the Royal Society of Canada.

Dr Ansari is interested in forging greater links between neuroscience and educatDaniel Ansari and team.jpgion, as part of the emerging field of ‘Mind, Brain and Education’. He is an associate editor of the peer-reviewed journals, ‘PLoS ONE’, ‘Developmental Science’ and ‘Mind, Brain and Education’ and he is the president of the International Mind, Brain and Education Society (IMBES).  IMBES supports the development of collaborative relationships between practitioners, researchers, and policy makers.

 Dr Ansari, together with Nadia Nosworthy, conceptualized and designed a Numeracy Screener and ran studies to investigate whether this test can explain individual differences in children's school-relevant math skills. The results showed the feasibility, reliability and validity of this measure, which is available free at the Numeracy Screener website.
