Magnus Botnan

Magnus Botnan is an Assistant Professor at the Department of Mathematics, Vrije Universiteit (VU) Amsterdam. He held a tenure-track position from 2018-2022, was a postdoc at TU Munich (2016-2018) under Ulrich Bauer, and earned his PhD at NTNU in 2015 under Nils A. Baas. His research spans topological data analysis, bridging pure mathematics (representation theory of quivers) with computational and applied aspects (persistent homology, data signatures).

• Education:
  • PhD in Mathematics at Norwegian University of Science and Technology (NTNU)
• Research Grants:
  • VIDI career grant (€850,000)
• Research Collaborations:
  • with Mike Lesnick, Ulrich Bauer, S. Oppermann, and S. Oudot

His recent work includes extremal Betti numbers, bottleneck stability, and signed barcodes for multiparameter persistence. He co-organized applied topology meetings in the Netherlands and supervises graduate students in computational topology.

Key scientific contributions:

• Advances in Mathematics
• Journal of Applied and Computational Topology
• SoCG conference proceedings

He teaches courses such as Calculus 2, Complex Analysis, and Topological Data Analysis at VU Amsterdam and Mastermath, with past courses in Differential Equations, Linear Algebra, and Modelling of Dynamical Systems.
