Research Summary
My research focuses on the structure and evolution of planetary mantles. The mantle of the Earth and of other terrestrial planets in (and beyond) the solar system are shaped by the processes of accretion (e.g., giant impacts), differentiation (magma ocean crystallization, partial decompression melting), solid-state segregation and convective mixing. Mantle present-day structures can be indirectly sampled by e.g. gravity measurements, seismic waves, or the chemistry of hotspot volcanism. To understand planetary evolution, my group and I explore numerical models of mantle convection, quantitatively comparing model predictions with geophysical observations and geochemical data. Using a similar multi-disciplinary approach, we also investigate regional models of mantle upwellings to understand the deep origin of hotspot volcanism, such as occurring in Iceland or Hawaii.
Outreach Highlights:
- Presentation about the inner workings of system Earth (and other terrestrial planets): the connection between surface tectonics & volcanism, mantle dynamics and sustainability of life-friendly conditions.Ìý
