I am a Professor of Philosophy at the National University of Singapore (NUS). I have two main research projects and a side project.

My first main research project is in philosophy of perception. Here I defend rich pluralism, which says that conscious perception consists of two very different kinds of sensory awareness that are exercised in concert: representational awareness of particulars and non-representational, partly essence-revealing awareness of sensory qualities.

My second main research project is in epistemology. Here I defend contextualism on broadly metaphysical rather than linguistic grounds. For instance, I argue that, as compared to invariantism, contextualism better honors the idea that knowledge explains action; it better respects the natural structure of epistemically significant kinds like justification and evidence; and it better accounts for chancy and inductive knowledge.

On the side, I also consider metaphysical questions about the nature of grounding.
