I work and teach primarily in metaphysics and the philosophy of science. My research has focused on using symmetries in physics as a guide to metaphysics. There are three parts to this project:

1/ Some of my work (Individuals, Absolutism vs Comparativism, The Bare Necessities, Quality and Structure, Substantivalism vs Relationalism) addresses first-order metaphysical questions about the nature of individuals, quantities, and space-time respectively. In each case I use symmetry considerations to motivate theses of a structuralist flavor.

2/ What is the content of metaphysical theses like these? Two papers (On the Plurality of Grounds, The Possibility of Physicalism) discuss a notion of ground that can be used to formulate a variety of metaphysical theses. And in Metaphysical Rationalism I relate this notion of ground to the Principle of Sufficient Reason.

3/ What justifies this use of symmetry as a guide to metaphysics? Two papers (Symmetry as an Epistemic Notion (Twice Over), Inexpressible Ignorance) develop the epistemology of this use of symmetry.

Papers in progress

Substantivalism vs Relationalism About Space In Classical Physics (Draft of August 2014)

...in which I survey a number of arguments for each view (including the bucket argument, Leibniz shift arguments, and symmetry arguments) and conclude that the case for relationalism is better than is often acknowledged.

Inexpressible Ignorance (Draft of July 2014)

...in which I discuss cases where ignorance is inexpressible (e.g. ignorance of absolute position, quiddities, and haecceities) and argue that the ignorance consists in an inability to identify things by way of their natures.

Publications

The Possibility of Physicalism forthcoming in The Journal of Philosophy.

...in which I argue that the notion of ground is suitable for formulating a variety of metaphysical theses including physicalism.

Metaphysical Rationalism forthcoming in Noûs.

...in which I develop and defend a version of the Principle of Sufficient Reason, one that entails that every truth is necessarily true.

Symmetry as an Epistemic Notion (Twice Over) forthcoming in The British Journal for the Philosophy of Science.

...in which I argue that symmetry is an epistemic notion (twice over).

Quality and Structure forthcoming in Current Controversies in Metaphysics, edited by Elizabeth Barnes (Routledge).

...in which I argue that the world is a purely qualitative mosaic. Here is the postscript, coauthored with Jason Turner.

On the Plurality of Grounds Philosophers' Imprint 14.14 (2014): 1-28.

...in which I argue that ground is an irreducibly plural notion: these are grounded in those. Cases of plural grounding include individuals and quantities like kilograms.

Absolutism vs Comparativism about Quantity Oxford Studies in Metaphysics: Volume 8 (2013). Winner of the 2011 OSM Younger Scholars Prize.

...in which I motivate and defend comparativism about quantities like mass.

The Bare Necessities Philosophical Perspectives 25 (2011): 115-160.

...in which I discuss substantivalism in the context of the General Theory Relativity, and argue that we do not yet have a satisfactory substantivalist theory.

Individuals: An Essay in Revisionary Metaphysics Philosophical Studies 145.1 (2009): 35-67.

...in which I argue that (fundamentally speaking) there are no such things as individuals.
