Reto Schnyder

General Info

I was formerly a postdoctoral researcher in the Applied Algebra Group of Professor Joachim Rosenthal at the University of Zurich. From 2018 to 2021, I was a postdoctoral researcher at the Department of Mathematical Sciences at Aalborg University in Denmark. I did my PhD between 2013 and 2017 at the University of Zurich.
