Frank Boers teaches EFL, EAP and diverse courses in descriptive and applied linguistics at the Erasmus College of Brussels and the Free University of Brussels, Belgium. His early research interests were lexical semantics (e.g. studies of polysemy) and figuration (e.g. cross-linguistic studies of metaphor), both approached from the vantage point of Cognitive Linguistics. Most of his recent research, however, concerns the acquisition of L2 vocabulary (including multiword units, such as idioms, phrasal verbs and collocations) and, more generally, the potential merits of introducing insights from Cognitive Linguistics (such as the notion of linguistic motivation) to language pedagogy. He is co-author (with Seth Lindstromberg) of Optimizing a Lexical Approach to Instructed Second Language Acquisition (Palgrave Macmillan, 2009), and co-editor (also with Seth Lindstromberg) of Cognitive Linguistic Approaches to Teaching Vocabulary and Phraseology (Mouton de Gruyter, 2008).
