A broad class of systems — including macromolecular materials, granular assemblies, and architected materials — is characterized by inherently multiscale structures. These structures are frequently disordered or amorphous, with intermediate organizations interconnected by weak interactions. Such systems display distinctive and often complex deformation and flow mechanisms, giving rise to geometric or material instabilities that are of significant interest in contemporary physics.
Our research addresses these phenomena across a diverse range of systems. To elucidate and quantify the relationships between mechanical response and multiscale structure, we develop and employ innovative experimental methodologies spanning all relevant length scales.
