Fields of interest:
I am interested in the formation and evolution of the continents. How did the continents originally form? Why are some continental regions stable for billions of years while others are repeatedly deformed? How does the composition of the deep lithospheric mantle relate to processes occurring at the surface? The main tool I use to investigate these questions is magnetotellurics (MT), which is a deeply-penetrating electromagnetic method that images the electrical conductivity of the lithosphere and asthenosphere. I seek to combine MT observations with constraints from mantle geochemistry, seismics and mineral physics to develop new insights into lithosphere composition and improve our understanding of continental evolution.
