Alan's research is directed towards understanding
the fundamental interactions that govern
a broad spectrum of geophysical processes.
Much of his work centers on the fluid mechanics, solid mechanics
and thermodynamics that control the
interactions between solids and fluids, especially near the melting
transition. He is
particularly interested in problems that span a range of
length and time scales, many natural examples of which
are further motivated by a desire to explore the
environmental conditions of the distant past. A central theme of his
research involves using homogenized
models to translate from the microscopic
length-scales over which the controlling physical
interactions operate, to the much larger
length-scales at which their effects are observed. Ongoing research
topics include investigations into
how the presence of premelted liquid at sub-zero temperatures can affect
the preservation of climate signals in ice cores, and what
role frictional heating and the melting of fault gouge plays in the dynamics
of earthquakes.
