Geochemistry and Dynamics of Earth

Geological phenomena such as faulting, earthquakes, volcanic activities, seafloor spreading, and mountain building that shape the topography of the surface of our planet find their roots in mantle convection and induced plate tectonics. At the Earth Science Department, researchers apply field investigations combined with geophysics, geochemistry, mathematics, and machine learning to understand the dynamics of the Earth and how the connection between the Earth鈥檚 interior and surface drives environmental processes, climates, and ecosystem structures. Faculty Members currently involved in this field of research include Mohammed Ali, Aisha Al Suwaidi, Alessandro Decarlis, Hamed Gamaleldien and Frantz Gerard Ossa Ossa.
