Leah Marshall manages the AAGL and oversees coordination with the ACE Isotope Lab for AMS radiocarbon analysis. Leah completed her PhD degree in Earth Sciences & Environmental Sustainability at Northern Arizona University in 2025. Her research investigates the impacts of past Arctic climate change on carbon cycling in permafrost and Arctic lakes. She uses a variety of geochemical, geochronological and biomarker approaches. She has undergraduate degrees in Geology and Environmental Science from William & Mary (2019).
Darrell Kaufman directs the AAGL. He has studied amino acid racemization beginning with his dissertation research at the University of Colorado. He specializes in using amino acid racemization to determine the ages and paleotemperatures of Quaternary marine and lacustrine deposits.
