The ILL runs a colloquium series at which prestigious speakers are asked to give exciting and accessible talks of general interest to scientists having a wide range of backgrounds. In the past, ILL colloquia have included the Astronomer Royal, the editor of Nature, Hélène Langevin-Joliot (Marie Curie's granddaughter), and Sir Tim Hunt (Nobel Prize 2001).

Because of the COVID19 pandemia, colloquia are currently by zoom, but they usually occur in the Chadwick Amphitheatre. They last about an hour and include ample time for discussion (when held in the amphi, both after the talk and afterwards over coffee.)

All staff and visitors to the EPN site are warmly welcomed.
If you are located outside the EPN site and wish to attend a colloquium (ILL ZAC access required), please contact Eliane Joly ( at least 3 weeks before the event .

If you have suggestions for future speakers, please contact Ulli Köster (

The titles and abstracts of forthcoming colloquia as well as those of previous colloquia are in the corresponding pages.
