Research Areas & Tools

The primary research focus of the lab is the use of natural abundance radiocarbon (14C) to determine the age and sources of carbon cycled in terrestrial ecosystems.

The laboratory features isotope preparation facilities for the analysis of natural abundance levels of stable (13C) and radioactive (14C) isotopes of carbon, as well as nitrogen (15N) and oxygen (18O).

These analyses are performed on variety of environmental samples from terrestrial ecosystems distributed globally.
