Research Interests

My research focuses on hydrothermal systems (black smoker vent sites) on the modern ocean floor and the formation of volcanogenic massive sulfide (VMS) deposits. I combine seafloor exploration and mapping with petrography, trace element geochemistry, and stable and radiogenic isotope techniques to investigate aspects of seafloor massive sulfide (SMS) formation, including:

  • Volcanic and structural controls on the location, size and composition of SMS deposits
  • Venting history, sulfide mass accumulation rates and temporal and spatial evolution of hydrothermal systems
  • Development and application of geochronological techniques for hydrothermal deposits (e.g., 226Ra, 210Pb, 230Th/234U)
  • Comparisons of modern SMS and ancient VMS deposits to better understand the preservation of extinct hydrothermal sulfide deposits on the seafloor
  • Develop exploration techniques such as Autonomous Underwater Vehicle (AUV) based high-resolution bathymetry and geological models for finding active and extinct hydrothermal systems
  • Develop global marine mineral resource estimates for SMS deposits, including size, grade and spatial distribution models
