Much of my work in semantics/pragmatics focuses on aspect, its interaction with temporal reference, and the lexical semantics of verbs.   I am also deeply interested in phenomena that have been labeled as involving “coercion” and the precise psychological mechanisms that underlie coercion-like interpretations and the observed processing cost.  With Maria Piñango, I  have been developing formal semantic analyses of  measure adverbs like  for an hour and aspectual verbs like begin, finish  that can be  reconciled in a precise way with  psycholinguistic and neurolinguistic observations. This work can be found here. This collaboration has also led us to begin exploring how to probe into the cognitive and neural mechanisms that are responsible for semantic change.
