Stefan Buijsman was born in Leiden in 1995 and obtained an M.A. in Philosophy at Leiden University in 2013. Before that he studied Computer Science and Philosophy, also at Leiden University. He wrote a B.A. Thesis in logic and an M.A. Thesis on assertion.

In 2016, he obtained his PhD at Stockholm University in the philosophy of mathematics. The dissertation aimed to establish the need for a philosophy of mathematics that pays attention to non-experts, and for more attention to empirical work on the psychology of mathematics.

Philosophical Interests: Philosophy of Mathematics, Philosophy of Mathematical Practice, Epistemology, Philosophy of Science.




The main topic of his research is the epistemology of mathematics, which naturally carries over into work on the ontology and semantics of mathematics. He is working in particular on the interaction between psychological and pedagogical research on mathematics learning and the epistemology of mathematics. As a result, the research is divided between properly philosophical work, and work on interpreting the empirical data.
