We study the evolution of Earth’s continental crust and lithosphere dynamics, seeking to understand how these processes have shaped the planet’s surface environment, long-term habitability, and the distribution of critical metals through geological time.

Our approach integrates quantitative petrology (e.g., thermodynamics, diffusion kinetics) and numerical geodynamic modelling with insights from field geology, geochronology, and isotope geochemistry.

We aim to address some of the most enduring and transformative questions in Solid Earth Sciences, including:

• When, how, and in what form did plate tectonics begin on Earth?
• What processes drove the formation of Earth’s first continents?
• How have tectonics and continental growth shaped Earth’s atmosphere, oceans, and habitability?
• Which processes lead to the enrichment of critical metals in granitoids and pegmatites?
