    Professor of Psychological Methods. 

    Head of unit Psychological Methods (https://psyres.uva.nl/content/research-groups/programme-group-psychological-methods/programme-group-psychological-methods.html)

    Distinguished research professor of Complex Systems in the Social and Behavioural Sciences at the Faculty of Social and Behavioural Sciences

    Han van der Maas (1966) studied Psychology at the University of Amsterdam and received his master (Psychological Methods) in 1989 and his Ph.D (Developmental Psychology) in 1993 for research on methods for the analysis of phase transitions in cognitive development (advisor: Peter Molenaar).  After a five year KNAW fellowship, he joined the faculty of the developmental group of the University of Amsterdam, first as associate professor and in 2003 as full professor. In 2005 he became professor and chair of Psychological Methods group at the University of Amsterdam.

    In 2009 he founded Oefenweb.nl, a spin-off company of the UvA-holding, selling an unique  game-based web-based adaptive child monitoring system.  Oefenweb is now part of Prowise.com.

    His general research theme is the formalization and testing of psychological theories in areas such as cognition, expertise, development, attitudes and intelligence.
