Research projects at IsoLab are primarily focused on the application of stable isotopes to the study of paleoenvironments and the evolution of the earth system.

We use water isotope (δD, δ18O, and 17Oexcess) data from ice cores to document past climate changes.

We measure changes in atmospheric chemistry using oxygen isotope (Δ17O) data from reactive nitrogen and sulfur compounds.

We examine the signature of mass extinction events using carbon isotope (δ13C) data in sedimentary rocks.

We measure carbon and oxygen isotopes (δ13C, δ18O) of carbonates and nitrogen and sulfur isotopes (δ15N, δ34S) from the oldest of rocks to investigate the environment for early biology.
