From April to the end of September of 2018 I was an interim professor at the Mathematical Institute of the University of Bonn. Homepage in Bonn

In October of 2018 I visited the Department of Mathematics of Shanghai Jiao Tong University.

In December of 2019 I will join the Department of Mathematical Sciences of Durham University.
