Several recent experiments identify unusual patterns in particle diffusion, hinting at some underlying complexity in the process which physicists have yet to discover. Through new analysis published ...

Around a decade ago, the discovery of Fickian yet non-Gaussian Diffusion (FnGD) in soft and biological materials broke up the celebrated Einstein's picture of Brownian motion. To date, such an ...

I study the statistics of many particles diffusing in a common, space-time random environment which introduces correlations in the movement of nearby particles. My work has shown that outlying ...

This diagram illustrates the distribution of charges on clay particles within a solution and the structure of the surrounding diffuse double layer. The diffuse double layer of clay minerals will form ...
