Postdoc Opportunities Fall 2019

  • In collaboration with the University of Texas at Austin, we currently have a 1.5-2 yr Postdoc position available to study ice-ocean interaction.

See Opportunities for more information about these projects.

Research Interests

My main research interests are the study the flow of glaciers and ice sheets and their interaction with the atmosphere and the ocean. I'm currently focusing on the flow history of the Greenland ice sheet and what we can learn from it to better predict future changes.

  • interaction between ice dynamics, calving, and fjord dyanamics
  • interaction between ice dynamics and orographic precipitation
  • mechanics and thermodynamics of glaciers and ice sheets
  • high resolution ice sheet modeling using the Parallel Ice Sheet Model (PISM)
  • stability of ice caps, tipping points
  • ice sheet model validation
