Assistant Professor of Earth Sciences

Research and Teaching Interests


My primary research interest is in modeling of the Earth's surface evolution driven by mantle convection and its interaction with the crust and surface process controlled by the atmosphere. I believe that the integration of independent geophysical techniques and geological observations provides a roadmap for a greatly improved understanding of the tectonic evolution of our planet.

A key ingredient in my research is the incorporation of observational constraints from varying fields such as seismology, geodesy, sedimentology, geochemistry, structural geology and geomorphology. This extensive list is made possible through a number of key collaborations across different fields that I have formed over the past few years.

Current Projects:

  • Geodynamic & Geomorphologic evolution of the southwestern US
  • African Topography throughout the Cenozoic; coupling of surface processes with mantle dynamics
  • Long term sea level change; the role of mantle and lithospheric dynamics
  • Numerical Modeling of Mantle & Lithospheric Dynamics



Courses

Numerical Methods In Geosciences, EAR 400/600, Fall 2011
Dynamic Earth, EAR 101, Spring 2012
Applied Geophysics, EAR TBD, Fall 2012


Students


I have an opening for a graduate student, MSc or PhD, interested in geodynamics, surface processes and/or the coupling of these across a wide range of space and temporal scales. My research is naturally open to collaborations across varying fields.
