Daniel Ansari (born December 26, 1975) is a German-Canadian cognitive neuroscientist and professor specializing in children's cognitive and neural development, with emphasis on numerical and mathematical skills and understanding. He is a Canada Research Chair (Tier 1) in Developmental Cognitive Neuroscience and Learning at Western University, Canada. He was a member of the college of the Royal Society of Canada from 2014 to 2017. He is also a Fellow in the Child and Brain Development Program of the Canadian Institute for Advanced Research. Ansari received the Boyd McCandless Early Career Award from the American Psychological Association. He was an Advanced Research Fellow of the Klaus J. Jacobs Foundation from 2018 to 2020.

Ansari has authored or co-authored over 150 journal articles and has over 27,000 citations on Google Scholar with a h-index of 87.

Education In 1999 Ansari completed his B.A. (Hons) in Psychology from the School of Cognitive and Computing Sciences at the University of Sussex.

He earned a Ph.D. from the Neurocognitive Development Unit at the Institute of Child Health, University College London, completed between 1999 and 2003.

During his doctoral studies, he became increasingly interested in neuroscience. He interrupted his PhD for a year to study for an MSc in neuroscience at the University of Oxford.

In 2003, Ansari became an assistant professor of education at Dartmouth College in the education department.

Career From July 2010 to July 2014, he served as an Associate Professor in the Department of Psychology Institute at Western University. From July 2014 to July 2018, he served as a professor.

Since July 2018, he has been serving as a Professor jointly appointed in the Department of Psychology and the Faculty of Education.

Within the international scholarly community, Ansari has held leadership roles in two learned societies devoted to his field. He served as Secretary (2012–2013), President-Elect (2013–2015), President (2014–2016), and Past-President (2016–2018) of the International Mind, Brain, and Education Society. He later chaired the Mathematical Cognition and Learning Society (2020–2021), after serving as Chair-Elect (2019–2020) and as a member of its governing board (2015–2019).

Numerical Cognition Laboratory For the past 20 years, Ansari has directed The Numerical Cognition Laboratory, a research group focused on understanding numerical processing, mathematical abilities, and the challenges some children face in early numeracy and math. The lab employs behavioral and brain imaging methods to investigate the cognitive and neural mechanisms involved in numerical cognition. The laboratory's work increasingly includes large-scale, cross-national, and registered-report studies on topics such as math anxiety and place-value understanding, alongside its behavioural and neuroimaging research on developmental dyscalculia.
