My research is broadly centered on fluid-rock/fluid-mineral interactions in the environment. This work has typically combined a suite of physical and geochemical observations with reactive transport modeling approaches.

I am currently a part of the Terrestrial Wetland Function and Resilience Science Focus Area, where my research consists of characterizing hydrological sources of inundation in ephemeral freshwater wetlands using a water balance model augmented by satellite-based surface water detection and the development of geochemical models that describe the interaction between organic matter and mineral surfaces in redox-sensitive systems.

Previously, I was at the University of Illinois where I used the stable lithium isotope system to quantify the reaction and transport pathways of rock-derived solute exports in small, pristine montane watersheds.
