My current research concentrates on the Main Ethiopian Rift from the perspective of geochemical and petrographical variation in the central rift. This central zone is considered a key transition zone between the continental rifting to the south and seafloor spreading to the north. My research investigates key magmatic processes associated with this transitional rifting and evaluates geochemical data in an extensive geophysical framework. This synthesis of geochemical, petrographic and geophysical data at this important location is a primary objective of the EAGLE project that sponsors this work.
