Research profile:

René's research has involved the integration of geochronological, structural, and metamorphic data to unravel the geologic evolution of complexly deformed and metamorphosed high-grade terrains. Her recent research has expanded to the field of economic geology with a keen interest in sustainable energy and mineral resource development.
