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.
