Jun Korenaga Professor of Geophysics The evolution and dynamics of Earth's mantle, in connection with its chemical differentiation, has been my primary research interest. It is a fascinatingly complex and fundamentally multidisciplinary subject, given the mantle's parental nature to the continental and oceanic crust, its thermal and chemical interaction with the core, and its potential role in the evolution of the hydrosphere. I'm a freestyle geophysicist, and my current research spans mantle and core dynamics, theoretical geochemistry, and marine geophysics.
