My research program focuses on the cognitive nature of bilingualism, with a specific emphasis on reading processes. My most recent studies have examined how it is that bilinguals resolve the lexical ambiguities that arise when one is proficient in more than one language. For example, there are many words that across languages are seemnigly similar but in fact map on to very different meanings. Now that there is abundant evidence that bilingual cannot simply turn off one of their languages, researchers need to address how it is that bilinguals handle the competition from multiple languages and eventually correctly identify and comprehend ambiguous words.
