My research focuses on using experimental, analytical, and numerical methods to improve our understanding of fundamental physics and mechanisms of fluid, gas, and solute transport in heterogeneous porous and fractured media. Our group studies a range of processes and due to the ubiquity of fluid transport in porous media, our work has important applications across a range of important environmental and geological processes including contaminant migration in the vadose zone, fluid flow through fractured systems, colloid transport in the subsurface, and carbon dioxide transport and immobilization in carbon storage projects. A detailed summary of current and upcoming projects and additional information about our group can be found here.
