Peter Indefrey is professor for psycholinguistics and neurolinguistics at Heinrich Heine University Düsseldorf (Germany) and research fellow at the Donders Centre for Cognitive Neuroimaging in Nijmegen.

Some of his favorite research topics are language processing in bilinguals, language production, semantic and syntactic processing, and reading. He studied medicine, psychology, philosophy, and linguistics and received doctoral degrees in medicine (1991) and linguistics (2002).
From 2001-2009 he headed the research projects Dynamics of Multilingual Processing (with Marianne Gullberg) and Neurocognition of Languge (with Peter Hagoort) at the Max Planck Institute for Psycholinguistics.
In 2009 he was awarded a Heisenberg professorship of the Deutsche Forschungsgemeinschaft (DFG).
Since 2011 he is Principal Investigator of two research projects of the DFG Collaborative Research Center (Sonderforschungsbereich) 991 The Structure of Representations in Language, Cognition, and Science.
Since 2013 Peter Indefrey is Managing Director of the Institute for Linguistics and Information Science at Heinrich Heine University Düsseldorf.
