We use computers to study multiscale phenomena and connect measurements taken on disparate length and timescales. Multiscale models provide a unique opportunity to investigate the emergent design principles of hierarchical materials. We tackle problems in both quantum and classical regimes with applications in both biological and artificial materials. The unifying theme of our lab is bottom-up modeling combined with systematic coarse-graining - i.e. we want to have a systematically improvable description of the dynamics which we use to develop a simple conceptual model to interpret experiments.
