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
