Laboratoire de Chimie Bactérienne (LCB), CNRS, 31 Chemin Joseph Aiguier, 13009 Marseille, France

Our lab is just 10 minutes from downtown Marseille: France’s second city, founded by the Greeks 600 years BC and only 15 minutes from the Calanques, a paradise for climbing, hiking, and sea adventures.

The perfect spot to enjoy city life or recharge on the trails between plasmid minipreps!
