We develop computational tools and design methodologies for advanced aerospace structures and materials. Our research focuses on areas including, but not limited to, data/AI-driven model-order reduction, high-fidelity solvers, nonlinear structural dynamics, multibody modeling, and design optimization, which are complemented by experimental testing and validation. Ultimately, our research contributes to making modern aerospace design more feasible in the face of ever-increasing complexity and heterogeneity.
