Arthur Bik's Webpage

I was a Postdoc.Mobility fellow at the University of Neuchâtel in the research group of Elisa Gorla from August 2023 to January 2024. Before that I was a postdoctoral member at the Institute for Advanced Study in Princeton for the 2022-2023 academic year and participant in the Special-Year Program on Dynamics, Additive Number Theory and Algebraic Geometry. I was a postdoctoral researcher at the Nonlinear Algebra group of Bernd Sturmfels at the Max Planck Institute for Mathematics in the Sciences in Leipzig, partly as a Postdoc.Mobility fellow. I obtained my PhD from the University of Bern supervised by Jan Draisma, I obtained my MSc from Leiden University supervised by Ronald van Luijk and Roland van der Veen and I obtained my BSc from Delft University of Technology supervised by Ronald van Luijk.
