My current research focuses on the oxygen, carbon, and nitrogen isotopic signature in organic material. This work/approach is focused on the calibration and reconstruction of the isotopic hydrologic cycle from terrestrial archives (tree rings and lake sediments) located in the US, Europe, and South America. Present work focuses on applying new continuous flow isotope ratio mass spectrometry (CF-IRMS) methods to biogeocemical orientated projects in the Everglades, The Keys, Florida Bay, and other tropical locations in South America. The goal of this approach is to better understand how changes in the hydrologic cycle and environmental conditions (nutrients, pCO2, stress, etc.) affect different biogeochemical systems, which aids in improving our understanding of past and present climatic change.
