Fernandez is a low temperature geochemist. Her research combines experimental and numerical modeling methods to constrain global water and elemental cycles, their relative feedback and responses to unprecedented land use changes and a rapidly changing global climate. A primary focus in Fernandez’s work is the study of fluid-rock interactions at near-surface conditions and how they manifest across various spatiotemporal scales from the mineral-water interface to regional scale river basins. Fernandez relies upon a variety of geochemical tools including stable isotope and trace element environmental tracers to fully characterize the diversity of biogeochemical and hydrologic processes that shape the dynamic landscapes and ecosystems characterizing Earth’s surface.
