Papers

• 4. Monodromy degree of temperate reduction curves. preprint [pdf]
• 3. The different for base change of arithmetic curves. preprint [ArXiv link]
• 2. Harmonic covers of skeleta. submitted. [ArXiv link]
• 1. Jumps of Jacobians via orthogonal canonical forms. published. (joint with Michaël Maex and Enis Kaya), Proc. Amer. Math. Soc. 153 (2025), 947–961, [Journal/DOI link] [ArXiv link]

I defended my PhD thesis in June 2025. It contains papers 1–4 above along with background material [pdf]. My supervisor was Prof. Dr. Johannes Nicaise (KU Leuven). Here are the slides of the public PhD defense, intended for a general audience (beware of major simplifications!)

Slides and posters

• slides: 'on a family of 2-dimensional wild quotient singularities' (CAGE, September 2025)
• poster: 'harmonic covers of Berkovich skeleta' (CIRM, January 2025)
• poster: 'the different function for covers of arithmetic curves' (Heidelberg, 2023)
• slides: 'pullback of weight functions and logarithmic differents' (Regensburg, 2022)

Outreach and miscellaneous links

Some upcoming plans

• 30 Sept 2026: educatief WOMO-congres in Leuven
• 17 Oct 2026: Wis Knutsel Festival in Gent
• 22 Nov 2026: Puzzle installation for MathFest 2026
in Ghent

I strongly support

• The viewpoints of Prof. Dr. Vladimir Lazić on the use of AI in research mathematics.
• The ICM out of USA boycott action: it is imperative that hosting countries respect human rights and protect basic democratic values.
• Belgian Universities for Palestine
