Research Interests Volcanic and tectonic controls on the distribution and characteristics of hydrothermal activity at mid-ocean ridges; geochemistry of rock-water interactions and the rate of the associated hydrothermal fluxes in global geochemical mass balances. In 2013, Humphris was elected a fellow of the American Geophysical Union who cited her "For sustained and exemplary contributions to our understanding of volcanic and hydrothermal processes at mid-oceanic ridges".
