Research Interests & Projects

Meso- to tectonic-scale geological processes are fundamentally controlled by nanoscale material processes including element and defect interactions in geomaterials. For instance, feedbacks between trace element mobility, fluids, and structural defects play a vital role in determining the rheology of geomaterials. In addition, the trace element and isotopic compositions of geomaterials are commonly used to provide pressure, temperature, and time constraints on geological events. Therefore, a deeper understanding of element mobility in the presence of structural defects is critical for utilizing and interpreting geochemical data. Investigation of these interactions, however, requires a correlative analytical approach involving high spatial resolution microscopy techniques. Past and current research topics include: 1) Influence of mineral microstructure evolution on crustal rheology; 2) Reliability of mineral chronometers and thermobarometers in deformed crust; 3) Post-emplacement remobilization of critical minerals and metals
