Research Focus

Julie is a broadly trained geoscientist with expertise in thermochronology, geochronology, and sedimentary basin analysis. Her research focuses on reconstructing ancient phases of mountain-building and erosion to understand how tectonics, magmatism, and surface processes interact to shape the Earth’s continental lithosphere.
