Dr. Lassiter's research focus is on the application of isotope and trace element geochemistry to fundamental problems of the Earth's origin and evolution, including but not limited to: Structure and chemical evolution of the mantle and crust; Origin of mantle plumes and nature of plume/lithosphere interaction; Generation and segregation of magma; Origin and chemical evolution of continental lithosphere; Chemical fluxes in constructive and destructive tectonic environments. Current areas of interest include the role of crust and lithospheric mantle recycling in the generation of mantle chemical heterogeneity, the origin and distribution of water and other volatile elements in the Earth's interior, and the thermal and chemical evolution of the Earth's core and core/mantle boundary.
