Current Research

I currently manage the Carbon, Water, and Soils Lab at the Forestry Research Laboratory in Houghton, Michigan. My lab prepares environmental samples for radiocarbon analysis, as a component of the Radiocarbon Collaborative (radiocarboncollaborative.org). We handle a wide spectrum of sample matrices including soils and sediments, dissolved phase organics, gases, and bones. After pretreatment, these samples are converted to graphite through combustion and reduction, and then sent to our partners at Lawrence Livermore National Lab for radiocarbon measurement by accelerator mass spectrometry. The data generated contributes to projects examining climate change effects on the carbon cycle, ecosystem health, and wildlife conservation.

Why This is Important

Radiocarbon (14C) is a unique and naturally occurring environmental tracer that allows researchers to track the flow of C among ecosystem components and estimate the mean residence time of C in these pools. Radiocarbon has applications in nearly all fields of environmental science, and allows unique insight into climate change effects on the terrestrial C cycle. Together with our partners at the Lawrence Livermore National Laboratory Center for Accelerator Mass Spectrometry and Michigan Technological University, we strive to develop applications of radiocarbon analysis that benefit a broad spectrum of researchers.
