Laboratory for the Psychology
of Child Development
André is a CNRS researcher (CR1) at the University Paris Descartes since 2018. His work is situated at the interface between Experimental Psychology, Cognitive Neuroscience and Developmental Psychology. After graduating in psychology at the University of Marburg (Germany) in 2001, he received his PhD at the RWTH University Aachen in 2006. André has been a post-doctoral researcher in the laboratory of Stanislas Dehaene (Neurospon, Saclay) between 2006 and 2009, and in the laboratory of David Melcher at the University of Trento (Italy) from 2009 to 2010 before joining Klaus Willmes’ laboratory in Aachen (Germany) as research associate between 2010 and 2012. Receiving funding from the Emmy Noether programme of the German Research Foundation allowed André to build and lead his own laboratory at the Humboldt University in Berlin (Germany) from 2012 to 2017. Before joining Paris Descartes University, he was a stand-in professor for Experimental Psychology at the Humboldt University from 2016 to 2017. His research is dedicated to the understanding of the cognitive and neural underpinnings of numerical cognition. He combines classical psychophysical methods with the analysis of structural and functional neuroimaging data from healthy participants across the life-span.
