My work centers on the use of large-scale computer
simulations to study the dynamics of disordered media
in several distinct systems. Although the systems differ greatly in
size and in the nature of the interactions between constituent particles,
the issues in each are similar. My collaborators and I seek new
ways to characterize a system that is out of equilibrium, such as a driven
system. We explore the interaction between quenched disorder and
intrinsic disorder, such as that induced by thermal melting. We also
study the types of structural information that can be extracted from
a system by driving it. This includes an understanding and a use of
dynamically-induced disorder-order transitions, which can alter transport
signatures and noise signatures in experimentally observable ways.
