The Earth is a complex machine.

We are scientists investigating the physics and chemistry of the Earth system. We use stable isotopes as our primary tool, exploiting natural variations in their abundances to unravel the inner workings of Earth's complex machinery. Our research spans a range of time and space: from microseconds to millennia, and from molecules all the way to the big blue marble.
