I’m employed by the University of Leeds to teach and research philosophy. I work in a cluster of areas: quite a bit in Metaphysics, and the Philosophy of Logic and Language, and in some areas of Epistemology and Philosophy of Mind.

I’ve supervised or co-supervised PhD theses on ontological commitment; the epistemology of mathematics; the semantics of definite descriptions; the metaphysical commitments of logic; and constructivism in mathematics. I’m happy to supervise students in any of my areas of research interest. In 2012-13 I will be teaching an advanced class in the philosophy of logic and mathematics.

I currently have three principal research projects:

• The nature of representation. (supported by the European Research Council)
• Life in a nonclassical world. (previously supported by the British Academy as part of the “Cognitive role of indeterminacy” project, Arts and Humanities Research Council as part of the “Metaphysical Indeterminacy” project.).
• Conditional thinking (previously supported by the British Academy as part of the “Cognitive role of indeterminacy” project).
