# Research

I am interested in understanding mechanical and hydrological processes
in the climate system, specifically processes that relate to mechanics
of granular materials, sea ice, and ice-sheet flow under past,
present, and future scenarios.  Investigations of fundamental
granular mechanics are important in many geodynamical and
geomorphological processes and settings, such as earthquakes,
landslides, sediment transport in flowing water, and dam stability.

I have listed my publications and submitted manuscripts below.  If
you would like to collaborate on a scientific problem please get
in touch.
