Helium isotope and rare gas geochemistry; isotope and trace element chemistry of volcanic rocks from mid-ocean ridges, islands, and continental rifts, with applications to the dynamics of the Earth's upper mantle; the role of volatiles in petrogenesis.
Spatial and temporal variations in helium isotopes along mid-ocean ridges, especially the ultraslow-spreading Gakkel Ridge (Arctic Ocean), the Galapagos Spreading Center, and the Lau Basin.
