Stein

I am a docteral student at the Radboud university in Nijmgen. My supervisors are Erik Koelink and Maarten van Pruijssen. Starting Fall 2026 I will be a postdoc at the MPIM Bonn.

My research is on quantum symmetric pairs and orthogonal polynomials.

In the past I studied in Utrecht and graduated under supervision of Marcel de Jeu.

Here is my CV.

In the spring of 2026 I will organize, together with Jort de Groot, an informal seminar on infinite dimensional quantum symmetric pairs and quantum gravity.
