Self Introduction
I am interested in better understanding how small-scale physical
interactions between solids and liquids can be appropriately represented in
simple predictive models of macroscopic geophysical processes. My visit to
ERI was motivated by the exciting work on granular dynamics that has been
conducted here by Takahiro Hatano and his former post-doc, Osamu Kuwano. A
puzzle that I have been working on concerns the relative scarcity of
macroscopic frictional melts along mature fault zones. My student, Jiangzhi
Chen, and I are pursuing the idea that changes to the thicknesses of shear
zones during earthquakes may be important for limiting the maximum
temperature rise and preventing macroscopic melting from taking place. I
welcome further discussion of related efforts and other research topics that
my group is engaged with, particularly those related to the rheology of
slow-slip earthquakes, subglacial drainage and the controls on glacier
sliding, and multiphase flow.
