Dr. Thibodeau uses isotopic measurements to decipher both the geologic and human past. In her research, she applies metals isotopes (Pb, Sr, Hg, U-Pb) as both tracers and chronometers of earth surface process and to questions of provenance, especially in archaeology. Her research areas include: the fate and source of trace metals (e.g. lead and mercury) in the environment, links between massive volcanism and mass extinctions in the geologic record, and determining the age of past fluid migration within potential repositories for nuclear waste. She also has an established history of collaboration with the archaeological community and applies isotopic tracers to identify or constrain the geologic sources of minerals, metals, and ceramics found in the archaeological record. To date, much of her work has focused on using isotopes to reconstruct the mining and exchange of turquoise by prehispanic groups in both the Southwest United States and Mexico.
