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 substance of the paper hard to read. Please consult the preprint for a cleaner version.**Modeling Metadisputes**

*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)

*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)
