Synopsis: How can you engineer a concept without changing the topic? It’s easy, just be clear about what the topic is.**The Logic of Hyperlogic. Part A: Foundations**

Synopsis: Some completeness theorems for hyperlogic, a logic for reasoning about other logics.**Does Chance Undermine Would?**

*Mind*(forthcoming) || preprint

Synopsis: A triviality result for counterfactual skeptics (and everyone else). Or: the main argument for counterfactual skepticism only shows most counterfactuals are chancy, not that they’re false.**The Dynamics of Argumentative Discourse**(with Carlotta Pavese)

*Journal of Philosophical Logic*(2022) || preprint

Synopsis: A dynamic semantics for argument connectives, like ‘therefore’, with applications to conditionals, imperatives, and induction.**Logic Talk**

*Synthese*(2021) || preprint

Synopsis: A hyperintensional expressivist semantics for regimenting claims about logic in the object language. No impossible worlds required.**Counterpossibles**

Synopsis: An overview of the counterpossibles literature.**Counterlogicals as Counterconventionals**(with Ethan Jerzak)

*Journal of Philosophical Logic*(2021) || preprint

Synopsis: Counterlogicals (and maybe all counterpossibles?) are only nonvacuous when interpreted as counterconventionals. Plus, a modern version of logical expressivism.**Comparing Conventions**(with Rachel Rudolph)

*SALT*(2020)

Synopsis: Metalinguistic comparatives are more expressions of comparative linguistic commitments than anything else.**Against Conventional Wisdom**(with Ethan Jerzak and Rachel Rudolph)

*Philosophers’ Imprint*(2020)

Synopsis: Conventional wisdom has it that truth is always evaluated relative to our conventions. Conventional wisdom is wrong.**On the Substitution of Identicals in Counterfactual Reasoning**

*Noûs*(2020) || preprint

Synopsis: If counterpossibles are opaque, then so are ordinary counterfactuals. This suggests that counterfactuals only have an epistemic reading.**A Two-Dimensional Logic for Two Paradoxes of Deontic Modality**(with Melissa Fusco)

*The Review of Symbolic Logic*(2020) || preprint

Synopsis: An axiomatization of Fusco’s two-dimensional deontic logic that solves Ross’s puzzle and the free choice problem.**Hyperlogic: A System for Talking about Logics**

Synopsis: A series of results comparing the expressive power of languages with two-dimensional operators.**On the Concept of a Notational Variant**

*LORI-VI*(2017) || preprint

Synopsis: There’s no single correct definition of a notational variant. Plus, a proof that there is a bijective translation from first-order logic into propositional logic that preserves entailment and nonentailment.**The Problem of Cross-world Predication**

*Journal of Philosophical Logic*(2016) || preprint

Synopsis: An analysis of cross-world predication (“I could have been taller than I am”) and cross-world quantification (“Everyone rich could have been poor”).**On the Expressivity of First-Order Modal Logic with “Actually”**
