Our work on the mechanical behavior of thin films and nanocomposites has tackled the important problem of simulating interface and interphase behavior at extended length and time scales. A newly established scale bridging technique called thermomechanically consistent coarse-graining (TCCG) developed for investigating polymer dynamics near surfaces with nanometer scale resolution has been instrumental in revealing mesoscale details that govern mechanical performance, while retaining crucial chemical details of specific polymers. Similar scale birding methods established for carbon nanomaterials are now being utilized to understand size-effects in bioinspired layer-by-layer composites arising from nanoconfinement. We are also extending our materials-by-design capabilities to composites beyond those that are inspired from nature, to explain surface and substrate effects in nano electronics, structural composites and coatings in the broader context of Integrated Computational Materials Engineering (ICME) and the Materials Genome Initiative (MGI).
