Description

This opportunity focuses on bridging processing parameters to material morphology and properties through advanced multiscale, multiphysics modeling. Ideal candidates will investigate complex fluid dynamics (e.g. non-Newtonian, multiphase) in agile manufacturing processes like additive manufacturing, liquid composite molding, compression molding, among others. Research will emphasize understanding how microscale interactions emerge into macroscale processing phenomena, particularly exploring nonequilibrium thermodynamic principles governing wetting and interfacial dynamics, multiphase fluid interactions, and processing-induced morphological transformations in composite materials. Of particular interest is the intricate, two-way coupling between material flow and morphological evolution, such as investigating how constituent dispersion and alignment (e.g., short carbon fibers, carbon nanotubes, liquid crystals) dynamically interact with rheology, and heat and mass transport.
