My work lies at the intersection of formal epistemology and philosophical logic. I am particualrly interested in (1) logics and quantitative formalisms combining notions of evidence, knowledge, and belief; (2) hyperintentional logics for representational propositional attitudes; (3) logics of reality oriented imagination; (4) the epistemology & logics of conditionals. Lately, thanks to my brilliant master and PhD students, I have also been thinking about logics of intention and social aspects of evidence sharing.
I am (still) a big fan of using topological semantics to model epistemic notions (see my dissertation Evidence in Epistemic Logic: A Topological Perspective).
