You can subscribe to a newsletter on this website. The newsletter provides selected updates, in particular on research, publications, talks, educational initiatives and related professional activities.
For the subscription, we process the data you provide, in particular your email address. Additional information, such as your name, is processed only if you provide it voluntarily.
