My main research interest is in the semantics of natural language, from both a theoretical and computational perspective. I am working on situation theory and situation semantics and am interested in using situation theory as a general metatheory for various different semantic theories currently being developed.
A particular focus of my research has been quantification in natural language. Previously I have carried out work in the Montague tradition, including the integration of Montague's semantics with transformational grammar, and the development of a technique of quantifier storage to account for scope interpretation and long-distance dependencies without complicating the syntax. I have recently been working on a situation theoretic approach to quantifiers.
I am interested how situation theory can be used to analyze aspects of language other than semantics, and also less specifically linguistic aspects of cognitive science such as knowledge and belief states and the way in which agents reason and interact with their environment.
