Research Interests

Second language acquisition, psycholinguistics, and oral fluency


  • Child and Second Language Acquisition
  • Introduction to Dutch as a Second Language
  • Language Acquisition Theories
  • Language and Thought
  • Teaching Dutch as a Second Language: Backgrounds (MA)
  • Testing and Assessment of Language Skills
  • Vocabulary Acquisition in a Second Language


How do adults learn languages? And how should languages be taught? My research aims to answer these questions by characterizing the changes in knowledge and processing mechanisms that are brought about by specific teaching methods, especially with respect to (morpho)syntax and speaking skills. My approach is driven by research questions from applied linguistics and psycholinguistics.

Until January 2013 I was the Principal Investigator on a research project funded by the Pittsburgh Science of Learning Center. We studied the effect of time pressure on the development of oral fluency in second language learners.
