Research Interests

  • Origins and formation of Earth and Mars, and other terrestrial bodies
    • Accretion and late veneer
    • Magma ocean (or not)
      • Volatile budgets
      • Setting the initial state
      • Solubility
      • Partitioning
  • Mantle and core geochemistry/petrology
  • Planetary scale volatile cycling
    • Interactions between mantle, atmosphere, and core
    • Through time
    • Slabs in the transition zone
    • Effects of variable fO2, pressure, temperature
  • Wish List:
    • Fully coupled planetary-scale model
      • geochemistry + geodynamics
    • Explain all the  weird stuff in the mantle
      • seen seismically
      • needed geochemically
        • size, mixing timescales, mechanical, chemical
    • Where, when, and how did plate tectonics start?
      • Why only on Earth?
    • Explain why Earth, Mars, Venus, and Mercury are so different
