Research

The broad aim of our research is to develop theoretical and computational methods combined with experiments for the assessment, design, optimization and manufacturing of novel materials and structures in various applications. In particular, we are interested in problems related to additive manufacturing of materials, hierarchical materials, multifunctional composites, and image-based (CT, MRI) multiscale modeling of biological materials.
