Research interests:

• Formal human-computer dialogue modeling (normative, public commitment-based approaches)
• Formal and computational pragmatics (normative, public commitment-based accounts of implicature and presupposition in human-computer dialogue)
• Pragmatic and semantic aspects of utterance generation in human-computer dialogue systems (illocutionary force, argumentative issues)
• Pragmatic motivations behind surface phenomena (ellipsis, connectors, free choice items, delocutive expressions)
• Discourse analysis (computational emulations of SDRT -- ``Segmented Discourse Representation Theory'')
