“I did my first postdoc at John lab where I learnt about the clumped isotope technique. Cédric is a very thoughtful and knowledgeable supervisor, he always took the time to teaching me about this exciting thermometer. Thanks to his enthusiasm I became very passionate about carbonate geochemistry and this experience was an important stepping stone for my future career. “

Research topics in the John lab are at the cutting edge of the respective field and provided me a fascinating insight in current scientific developments. They were a strong motivation for my own research. A vibrant and motivated research group inspired exciting project ideas and enabled thorough scientific discussions."
