  • Now studies mathematics at the University of Toronto, having completed a first year of the bachelor's program and praising the department's reading courses and academic advising; the move abroad continues a trajectory from national competition to a large research department.Jun 1, 2025
  • Tied for first place in Skolornas matematiktavling 2023, Sweden's national mathematics competition, sharing the title with John Hedin of Lund.Dec 5, 2023

  • Won the competition while at Hvitfeldtska gymnasiet in Gothenburg, having been introduced to it only when starting gymnasium, so a national title within roughly three years of entry suggests unusually fast mathematical development.Jun 26, 2024
  • Named a reserve for Sweden's IMO 2024 team (Bath, UK), so he remains inside the national selection pipeline after 2023.May 2024
  • Studying at U of T is funded partly by Anna Whitlocks minnesfond, a scholarship supporting Swedish students studying abroad, which he cites to offset the high international tuition.Jun 1, 2025
  • Presented an AMACSS colloquium, 'Symmetries of Geometric Objects', engaging students with group theory, an early sign of interest in pure mathematics beyond coursework.Nov 2024
  • Selected for Sweden's 2023 IMO team alongside Erik Hedin, John Hedin, Mikael Haglund, Jiachen Mi and Ivar Angquist, with team leader Victor Ufnarovski.Jul 2023
