I study the chemistry of water and its reactions with minerals and rocks. Through these reactions, water acquires chemical constituents and isotopic signatures. The chemical and isotopic signatures are useful to map the movement of fluid flow and allow us to calculate the in situ rates of chemical reactions under geological conditions. On a global scale, these chemical reactions are a key component of the interactions between the Earth’s hydrosphere, lithosphere, biosphere, and atmosphere. Many fundamental processes in Earth’s geological systems, such as chemical weathering, diagenesis, and the movement, distribution, and global cycling of chemical elements are related to these interactions.
