In addition to talks related to my research, I've also given some lectures for bachelor or master courses. See my CV for my teaching experience.

If you would like to have slides from any of my talks, feel free to send me a message. (I will try to gradually add them to my website.)


I sometimes write some notes for friends and colleagues. These are typically hard to read without context, will not include the necessary references and will include errors. But maybe they are still useful for some people...

  • My master thesis was on Rational Homotopy Theory, supervised by Ieke Moerdijk. Rational homotopy theory is concerned with algebraic invariants of topological spaces. Invariants such as homotopy groups are notoriously hard to compute, but very useful in mathematics. To simplify things, we can rationalise them (that is, using rational numbers instead of integers). This way, the invariants are easier to compute. [ PDF ] [ Github ]

  • My bachelor thesis was on the Dold-Kan Correspondence, supervised by Moritz Groth. The Dold-Kan correspondence is an equivalence between categories: on one hand there is the topological category of simplicial abelian groups and on the other hand there is the more algebraic category of chain complexes. This is a key result in algebraic topology, especially homology. [ PDF ] [ Presentation ] [ Github ]
