Much of my research has focused on lunar paleomagnetism and placing constraints on the temporal evolution and decline of the (now extinct!) lunar core dynamo field.  Establishing the lifetime and intensity record of the lunar magnetic field has implications for the dynamo generation mechanism and the thermal evolution of the Moon.

I also study the physical effects of impact cratering events on planetary surfaces.  Understanding the interplay of shock, impact heating, and hydrothermal alteration processes on target rocks will allow us to better understand the magnetic signatures of cratered surfaces on other planetary bodies.  I am currently a member of the Science Party for IODP Expedition 364, where I am studying the paleomagnetism of Chicxulub crater.
