Research Focus

My dissertation concerns the meanings and logics of conditionals, both subjunctive and indicative. I am particularly interested in the truth conditions of backtracking counterfactuals, and the relationship between our English indicative conditional and the material conditional. I also maintain a research interest in the history of analytic philosophy, particularly Quine's views about language and how they impact his views in philosophy of science and ontology.
