Geant4-DNA 2026 Collaboration Meeting

Oct 13, 2026, 10:00 AM → Oct 14, 2026, 5:00 PM Europe/Paris

Marie Curie room (LP2i Bordeaux)

The 2026 Geant4-DNA Collaboration Meeting will take place at the Laboratoire de Physique des deux infinis (LP2i, CNRS & Bordeaux University), in Gradignan, near Bordeaux, France. 

The first day and the morning of the second day will cover the work plan, while the afternoon of the second day will be dedicated to the Steering Committee meeting. Remote participation will be possible.

On-site participants are kindly invited to handle their trip arrangements (travel, housing).

Note that the annual Geant4 Collaboration Meeting will take place Oct. 5-9 in the city center of Bordeaux, France, at a different location from the Geant4-DNA Collaboration Meeting (in Gradignan).

We look forward to welcoming you at the LP2i !

Sebastien Incerti, Dousatsu Sakata, Hoang Tran
