Mobility in Glasses and Liquids

This group works to understand and predict mobility in glasses and supercooled liquids with atomic resolution over timescales of seconds or longer. They conduct unique, nanoscale, time-resolved experiments and simulations leveraging new methods in physics-aware, machine-learning.

The combination of atomic resolution and long times will lead to fundamental understanding of glass behavior including viscosity, fragility, and relaxation, as well as the ability to predict crucial glass properties such as plasticity and impurity diffusion from composition and thermal history.

The IRG’s scientific developments will enable rational design of organic and inorganic glasses, which the group will leverage to create high-mobility, anisotropic organic semiconductor glass films for organic electronics and stabilized, confined, drug molecule glasses for pharmaceutical preparations.
