Dr Ansgar Endress trained as a generalist engineer at École Polytechnique and obtained a doctorate in Cognitive Science from the École des Hautes Études en Sciences Sociales. Before joining City University London, he has been a post-doctoral fellow at the International School for Advanced Studies, Harvard University and the Massachusetts Institute of Technology. He is also a visiting researcher at Universitat Pompeu Fabra, Barcelona.

Dr Endress studies the psychological mechanisms involved in language acquisition and use. He is particularly interested in evolutionarily ancient perceptual and memory mechanisms, and how they support a diverse set of computations in language acquisition. More generally, he is interested in reducing complex cognitive phenomena to basic psychological mechanisms in domains ranging from memory processing to theory of mind.
