[2] He is a collaborative author of The Cambridge Grammar of the English Language, has co-authored Information Status and Noncanonical Word Order in English, authored The Semantics and Pragmatics of Preposing, and co-edited Drawing the Boundaries of Meaning: Neo-Gricean Studies in Pragmatics and Semantics in Honor of Laurence R.

He found that the fall-rise intonational contour contributed pragmatically to the utterance interpretation by conveying speaker uncertainty.

[7] Also with Hirschberg, he has worked on a series of utterance pairs and investigated the effect of pitch range, duration, amplitude and spectral features, regarding the interpretation of rise-fall-rise intonational contour.

[9] With collaborator Richard Sproat, he applied psycholinguistic experiments to support the view that outbound anaphora is grammatical and its felicity determined by pragmatic principles.

He also highlighted the effect of concepts placed in syntactically prominent positions on text processing and short-term memory accessibility.

With Betty Birner, he highlighted various classes of word orders (in English and other languages) in the context of their information‐status constraints.
