Bruce Nelson

Bruce Nelson is professor in Earth & Space Sciences, and adjunct professor in the School of Oceanography. He is PI of the Isotope Geochemistry Laboratory, which includes mass spectrometry for high-precision analyses of radiogenic and stable isotope ratios, and clean labs for sample processing.

Bruce’s research interests include origin and evolution of continental crust, seafloor hydrothermal processes, and geochemical evolution of the earth’s mantle. He measures variations in trace element concentrations and long-lived radiogenic isotopes (e.g., Pb, Nd, Sr, Hf) to investigate early earth evolution, and fractionation of non-traditional stable isotopes (e.g., Cu, Zn, Fe, Mg) to investigate low temperature geochemical and biological processes.
