Hello! I do mathematics and hold a postdoctoral research position at the Department of Mathematics, Royal Institute of Technology, supported by the Knut and Alice Wallenberg Foundation. I am part of the Dynamical Systems group.
Before this I held a postdoctoral research position at Laboratoire de Mathématiques d'Orsay, Université Paris-Saclay, hosted by Jacek Graczyk and supported by the Knut and Alice Wallenberg Foundation. Prior to this I was enrolled in the Junior Fellowship Program at Institute Mittag-Leffler.
I was awarded my PhD at the Centre for Mathematical Sciences at Lund University, and was a member of the Dynamical Systems group. My supervisor was Magnus Aspenberg.
Here you can find me in the Mathematics Genealogy Project.
I am co-organizing the Dynamics Seminar at KTH, and its schedule can be found here.

I do research in low-dimensional real and complex dynamics. In particular, I am interested in the recurrent behaviour of critical points.
