research

I have a rather broad range of research interests, which includes philosophical issues, technical work and more application-oriented topics. Below is an incomplete overview:


:: logical geometry: generalizing and re-analyzing the traditional square of opposition; connections and differences between the various types of logical diagrams (Aristotelian diagrams, opposition diagrams, implication diagrams, Hasse diagrams, duality diagrams, etc.); bitstring semantics; algebraic perspectives on duality in logic and language; the visual-cognitive properties of logic diagrams; etc. (for more information, see the project website)

:: history of logic: Aristotelian diagrams in specific historical authors (e.g. John Buridan, Nicole Oresme, Domingo BaƱez, Juan Caramuel y Lobkowitz, Arthur Schopenhauer, Augustus De Morgan); the history of logic at the University of Leuven (with a special focus on the 15th and 16th centuries); development of a comprehensive digital database of Aristotelian diagrams used throughout history

:: philosophy of logic: the various roles of Aristotelian diagrams in logical practice

:: epistemic logic and formal epistemology: probabilistic epistemic logic (with applications in game theory, e.g. Aumann's agreeing to disagree theorem); the Lockean thesis on belief vs. degrees of belief; the philosophical significance of the dynamic turn in epistemic logic

:: natural language semantics and philosophy of language: the semantics and pragmatics of indefinite/definite descriptions; generalized quantifier theory; vagueness; bitstring semantics for various lexical fields; scalar implicatures

:: history of philosophy: William of Ockham's theory of cognition

:: mathematical modal logic: algebraic and topological models for modal logic; probabilistic extensions of modal logic
