Dr Hamish Brown

I'm a postdoctoral fellow in Geodynamics at the Australian National University. My research is focussed on the link between flow in the Earth's mantle and resulting surface processes such as vertical motion and intraplate volcanism. Convection in the Earth's mantle induces large scale vertical motion of the Earth's surface over millions of years, termed dynamic topography. I work on mapping this large scale uplift and subsidence through time using a variety of forms of geological evidence, and comparing this to the dynamic topography predicted in global fluid dynamics simulations of the mantle. By making these comparisons we can better understand Earth's dynamic history, the fluid dynamics of mantle convection, and consequently, the physical structure of the deep Earth.
