Ingrid Christoffels is a postdoctoral fellow at Cognitive Psychology Leiden University, the Netherlands. She currently works on language control in speaking, language switching, translation and self-monitoring, using fMRI, EEG, and behavioral measures. In general, she is interested in neurocognitive and experimental approaches to cognitive control, language and bilingualism, executive functioning, working memory, and individual differences.   Read more on her homepage: www.christoffels.eu
