Design of material systems with complex microstructures represents the future of materials development to achieve unprecedented product performance. While most of the existing methods are trial-and-error based, we are proposing data-driven systematic computational design methods that provide a seamless integration of design optimization, predictive materials modeling, processing/manufacturing, and data/informatics to enable the accelerated design and development of advanced materials systems. In this talk, we will introduce the state-of-the-art computational design methods for designing heterogeneous nano- and microstructural materials systems such as polymer nanocomposite, nanodielectric polymers, light-weight composite structures, and thin-film solar cells. Research developments in microstructure characterization and reconstruction, deep machine learning of key microstructure features, data-driven Bayesian optimization for mixed variables, and multiscale uncertainty quantification will be introduced. Challenges and opportunities in designing engineered material systems will be discussed.
