About the McGee Lab

Our work builds records of past climate changes using geochemical tools, with a focus on applications of uranium-series isotopes.

In marine sediments, we use uranium and thorium isotopes to quantify accumulation rates in an effort to understand changes in the emission and transport of dust from the world’s drylands.

In speleothems and lake carbonates, uranium and thorium provide precise and accurate dating of changes in water balance and precipitation source. Building on these chronologies, we can compare records from different locations to build a global picture of past climate changes.
