I am a postdoctoral researcher at the Central European University, within the MODREQUAM project. I obtained my PhD at Scuola Normale Superiore, under the joint supervision of Mario Piazza (SNS) and Igor Sedlár (Czech Academy of Sciences).

My research lies at the intersection of (non-classical) logic and formal epistemology. More in details, here are some topics I've been thinking about recently, in order of decreasing frequency:

• Relevant and substructural logics;

• Formalisation of epistemic attitudes;

• Hyperintensional logics;

• Dynamic epistemic logic;

• Philosophical aspects of logical connectives;

• Topic sensitive logics;

• Logical Pluralism;

• Deontic logics.
