I work primarily at the intersection of metaphysics and philosophy of language, with a special focus on issues related to vagueness, indeterminacy of meaning, and meta-ontology. I have additional interests in meta-ethics (esp. expressivism), philosophical logic, formal epistemology, and rational choice theory.
I grew up in Flint, Michigan and attended Columbia University in New York City where I studied economics and philosophy. After a brief stint in investment banking, I returned to my home state to pursue a PhD in Philosophy at the University of Michigan.
I am currently an assistant professor at Toronto Metropolitan University (formerly "Ryerson University"). Beginning in the Fall of 2022, my partner, Mercedes Maria Corredor, and I will be joining Virginia Tech as assistant professors.
The indeterminacy considerations raised by Hilary Putnam have motivated the thought that, among the semantic values for predicates, some are more eligible than others. I extend these Putnam-style considerations to include the semantic values for logical vocabulary. The result is a new argument for Ted Sider's thesis that some candidate semantic values for our logical vocabulary are more eligible than others.
Shamik Dasgupta and others have argued that individual identities (e.g. an individual's haecceity) cannot be detected and therefore should be excised from our fundamental ontology. I defend individual identities. Unlike extant defenses, my defense targets the claim that these identities cannot be detected.
Entry on Vagueness

Overview on philosophical investigations in vagueness (aimed at undergraduate audiences)
(forthcoming at The Journal of Philosophy)
I explore the relationship between (i) quantifier variantism (ii) vague existence and (iii) metaphysical vagueness. I argue that the quantifier variantist is committed to a particularly robust sort of vague existence, which entails a subtle and novel sort of metaphysical vagueness. Along the way, I clarify the notions of vague existence and metaphysical vagueness, and offer new arguments linking restricted composition to vague existence and linking vague existence to metaphysical vagueness.

Kit Fine introduced the notion of grounding in order to help us state and resolve so-called "questions of realism". Ted Sider has argued that his notion of metaphysical semantics is better suited for the task. I disagree and defend the grounding theorist.
I explore the conception of a "semantic rule" underlying Thomasson's modal normativism, especially in the context of a posteriori necessities.

Discussion of the meta-ontological thesis of quantifier variance
(published in Ethics)
I use conceptual role semantics for moral terms to explain moral vagueness without ontic vagueness, responding to the argument in Schoenfield (2016) that moral vagueness is ontic vagueness.

I propose a view that mimics genuine metaphysical vagueness, according to which the term 'natural' and its cognates are vague and the source of the vagueness is semantic.

Using tools from the problem of the many, I argue that the best account of vagueness is one in which we are simultaneously speaking many languages, tokening many sentences, and asserting many propositions.

I explore, in the context of Elga's (2010) dutch strategy, a decision rule for agents with imprecise or vague credences.
