I am interested in the interior of the various planets in our solar system. I want to understand the difference in their internal structure and in particular the dynamic processes that operate inside the planets. Slow convection in the "solid" rocky mantle of the terrestrial planets gives rise to volcanism that shapes the surface of a planet or that has led to the formation of an atmosphere. Flow in the electrically conducting cores of some planets drives a dynamo process that generates a magnetic field, which shield the atmosphere and the surface of the planet from the energetic particles of the solar wind. Convection inside the giant gas planets is probably the cause for the strong zonal winds that give these planets a banded appearance. Targets of interest are all objects that are large enough to be internally differentiated (e.g. in crust, mantle and core), which includes big satellites and "dwarf planets" such as Vesta. I am also interested in the planetary aspects of our home planet Earth. The overarching aim is to learn what is common and what is different in the various planets and what made Earth special, so that it maintains conditions suitable for life.
