The successful candidate will join an innovative research program that is characterizing individual variation in language skills at behavioural, neurobiological, and genetic levels, an initiative of the Language in Interaction (LiI) consortium, sponsored by a major grant from the Netherlands Organisation for Scientific Research. The LiI consortium has developed a computer-based test battery to assess core skills underlying speaking and listening across a broad spectrum of abilities, and has already applied this to hundreds of young adults from the general population, a subset of whom are also tested with functional MRI. In parallel, saliva sampling has been used to collect DNA. The postdoctoral scientist will take the lead on the genetic aspects of the project. Specifically, they will process and analyse genome-wide genotype data from this unique resource, and use methods for analyzing polygenic contributions to human traits in order to trace genetic links to cognitive skills, childhood learning disorders, and MRI-based measures of brain structure/function, integrating with independent datasets available at the Language and Genetics department. The project will be further scaled up by applying online versions of the LiI battery to large pre-existing population-based cohorts with available genome-wide genotypes. The postdoctoral scientist will also foster connections to ongoing work by GenLang, an international network of researchers carrying out genetic association meta-analyses of multiple speech/language/reading-related cohorts across the world.
