Electrophoretic deposition (EPD) is an academically and industrially relevant process for colloidal crystal, ceramic, and advanced functional material production. Despite its widespread long-term usage, underlying mechanisms of deposit formation and microstructure evolution during EPD remain poorly understood due to limitations of destructive experimental probes and available models that disregard the particle-based nature of deposits. Part of my research focus is to develop and evaluate predictive models that compute inter-particle interactions explicitly to provide previously inaccessible information about colloidal packing within empirically relevant EPD systems. Our simulation results offer new and surprising routes to control the density and degree of ordering during EPD beyond commonly suspected approaches. Furthermore, we use the model to explore reversible EPD systems in which properties of the electric field and colloidal suspension properties influence the resuspension rates of colloidal deposits
