My research focuses principally on the philosophical foundations and applications of formal theories of rational choice and inference, spanning topics in the philosophy of science, epistemology, philosophical logic, artificial intelligence and decision theory.

I have recently been awarded a 4-year Future Fellowship by the Australian Research Council, for a project titled `Qualitative Models of Rationality: Philosophical Foundations and Applications' , a substantial proportion of which will be devoted to providing a logic of evidential relevance, grounded in the so-called AGM model of belief change, a powerful and elegant framework that has surprisingly seen very few philosophical applications to date. Further details to follow soon.
