As soon as you arrive in the lab, it would be great to introduce yourself to everyone.

If you're an intern/phd-student/postdoc, ask your advisor to introduce yourself to everyone.
Most importantly, go see the unit's director Georges (bureau 410), and the gestionnaires Marie-Nicole (bureau 416) and Malika (bureau 408).

If you're a Ph.D. or postdoc, you also have to meet Raphaël Candelier for creating a website/cloud account and be added to the mailing-list.
