  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 B: Extensions and Restrictions
  Review of Symbolic Logic (forthcoming) || preprint
  Synopsis: Some more completeness theorems for hyperlogic, with applications to counterpossibles and logical omniscience.

  Synopsis: Some completeness theorems for hyperlogic, a logic for reasoning about other logics.
• Does Chance Undermine Would?*
  Mind (2022) || 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.
  *Between when the online-first version came out and when the article was assigned a volume and issue number, many formatting and typesetting errors were introduced to the publication. (Don’t ask me how…) These errors make the substance of the paper hard to read. Please consult the preprint for a cleaner version.
• Modeling Metadisputes
  23rd Amsterdam Colloquium (2022)
  Synopsis: Can a dispute over whether a dispute is verbal be verbal? Yes.
• The Role of Questions, Circumstances, and Algorithms in Belief (with Jens Kipper and Zeynep Soysal)
  23rd Amsterdam Colloquium (2022)
  Synopsis: Question-sensitive accounts of belief do not solve the problem of logical omniscience. Maybe a more general account can.
• 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
  Philosophy Compass (2021) || preprint
  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
  22nd Amsterdam Colloquium (2019)
  Synopsis: A new formal system for talking about other logics.
• Counteridenticals

  Synopsis: If you were me, you too would think identity is contingent.

  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”).
