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
