She has also held appointments as a lecturer in the Linguistics department at Harvard University and as a postdoctoral researcher at the University of Illinois at Urbana-Champaign. Her research combines experimental and corpus linguistic approaches to psycholinguistics. Her interests include probabilistic models of language production and comprehension at the levels of phonology, morphology, and syntax, and language disorders. Her publications include "Knowledge of grammar, knowledge of usage: Syntactic probabilities affect pronunciation variation," and "Knowledge of grammar includes knowledge of syntactic probabilities" (both with Susan Garnsey, Language 2004 and 2006); a Special Issue on Exemplar-based Models in Linguistics in The Linguistic Review (edited with Alan C. L. Yu), and "Thyme and time are not homophones: The effect of lemma frequency on word durations in spontaneous speech" (Language, 2008).
