GEG - Geothermal Energy and Geofluids

Research Interests

My research interests are fractures and fluid flow. My current project is visualizing and quantifying fluid flow and solute transport in fractures in 3-Dimensions: using 3D printing, particle image velocimetry (PIV), and Laser-induced fluorescence. The project aims to understand the mixing behavior at fracture intersections.
