Hei! I am a postdoc in the workgroup Inverse Problems supervised by Prof. Dr. Thorsten Hohage. I worked two years on a project related to energy disaggregation at the University of Graz, Austria, following my doctoral research on bifurcations in periodic integrodifference equations at the University of Klagenfurt, Austria. I have picked up a fair bit of German over the years, but I still remember how to speak Norwegian!

research interests

  • inverse problems
  • energy disaggregation
  • non-convex algorithms
  • bifurcation theory
