How do human infants acquire their native language with such astonishing speed and efficiency? Our laboratory examines the role of the social environment in rapid language acquisition. Using behavioral and brain imaging techniques, we seek to discover and define mechanisms through which social factors and environments influence the early acquisition of speech sounds and words. What is the role of different social cues during the learning process? How does learning change as a function of an infant’s age and environment? In answering these questions, our goal is to develop useful theoretical frameworks and practical tools to measure and improve language learning in infants.

Biography
After undergraduate studies in Psychology at Humboldt University in Berlin, I became fascinated with infant language development during a research stint in the Laboratory for Language Development at the RIKEN Brain Science Institute. I earned a Ph.D. from the International Max Planck Research School for Language Sciences at Radboud University and the Max Planck Institute for Psycholinguistics, followed by postdoctoral research at the Infant Language Center at the University of Pennsylvania and Laboratory of Cognitive Sciences and Psycholinguistics at Ecole Normale Supérieure.
