I am an Associate Professor in the Department of Philosophy at the University of Hong Kong. My research falls mainly into the areas of Metaphysics, Philosophy of Language, and Philosophy of Science. I also have interests in Epistemology, History of Modern Philosophy, Metaethics, and Philosophy of Logic.

Much of my recent work has focused on the nature of truth and truthmaking. My first book, The Primitivist Theory of Truth, defends the view that truth is an undefinable primitive concept. My new book, A Theory of Truthmaking, defends my novel approach to truthmaker theory. I have also published on the topics of deflationary truth, moral realism, scientific realism, Tarski, modality, theories of ontological commitment, presentism, and the liar paradox.
