Research interests

Dr. Brian Kendall is an assistant professor who applies isotope geochemistry (both metal stable isotope systems and radiogenic isotope systems) to a wide variety of Earth Science research topics. Current research includes: 1) the co-evolution of Earth surface oxygenation, metal biogeochemical cycles and biological evolution over time, including the development and application of paleo-seawater redox proxies, and elucidating secular variations in seawater metal isotope compositions over time, 2) metal isotope geochemistry of petroleum and implications for oil-oil and oil-source rock correlations, 3) metal isotope geochemistry and geochronology of ore deposits and implications for exploration, and 4) sedimentary geochronology using the Re-Os isotope system.
