Our research has focused on a broad range of problems in the area of Earth system structure, dynamics and evolution. Some of the topics we are currently investigating include:

  • ice age dynamics, gravity anomalies and sea level change
  • tidal tomographic imaging of deep mantle buoyancy
  • mantle flow, dynamic topography and the geological record
  • critical events in Earth’s paleoclimate history
  • solid Earth and sea level impacts on early and modern human migration
  • 3-D variability of mantle viscosity
  • modern global warming and sea level change
  • long term rotational stability of Earth and terrestrial planets
  • anelastic behavior from seismic to ice age time scales
  • geodetic measurements of crustal deformation and gravity
  • ancient eclipse observations as unique constraints on Earth rotation
  • coupled modeling of landscape evolution, marine ice sheet stability and sea level change
