Research Focus: Medieval and modern philosophy of language and logic, with specialized work on figures like Walter Chatton, Thomas Aquinas, and William of Ockham. His research bridges historical analysis with contemporary philosophical logic and semantic theory.

Recent Publication Trends: Current works examine future contingents, supposition theory, and possible-worlds semantics in medieval contexts. He explores prophetic language ontologies, anti-relativist arguments in Plato, and formalist/ontological tensions in pre-Kantian philosophy.

Scientific Contributions:

• DFG-funded project on Cicero's philosophical methodology
• Book: Walter Chatton on Future Contingents (Brill, 2017)
• Collaborative research with Sonja Schierbaum on Ockham's logic
