Ventotene (LT), Italy, 11-16 September, 2023

In memoriam of             Robert J. Zimmer

5 November 1947 - 23 May 2023

The workshop will take place in Ventotene, Italy from the 11th until the 16th of September 2023.


In addition to research talks there will be an instructional component in the form of three minicourses. Doctoral students and young researchers are particularly encouraged to apply.


In accordance with the Statement of Inclusiveness , this event will be open to everybody, regardless of race, sex, religion, national origin, sexual orientation, gender identity, disability, age, pregnancy, immigration status, or any other aspect of identity. The island of Ventotene is where the seed of a border-free Europe was planted, and hence is a location of symbolic importance regarding inclusiveness.
