Simos Gerasimidis

Assistant Professor

Research areas lie in the areas of structural stability, thin-walled structures, nano- and micromechanics, new architected metamaterials, infrastructure resilience, bridge engineering, new metamaterial designs for engineering biofilm, structural systems and energy structures. His research activities have aimed at studying the behavior of structures and new cellular truss-lattice metamaterial architectures to localized damage and defects, as well as identifying novel applications for metamaterials. He has been active in the field of infrastructure resilience, structural response of critical infrastructure systems subjected to extreme-loading events in urban regions, resilient-oriented structural design approaches, damage propagation and structural response of damaged or deteriorated structures covering a broad spectrum of structural behavior.

Current Research

We are currently studying the effect of defects in nano- or micro-lattice architected metamaterials. This research work is performed through the collaboration with Prof. Bertoldi's research group at Harvard University. We are investigating the response of topologically distinct truss-lattice architectures to the inclusion of defects in order to elucidate how defects influence the elastic properties of these materials. We are exploring comparisons between the elastic properties of highly connected lattice-truss materials respond to defects in the same manner as homogeneous materials. Additional work focuses on 3D Printed Biomimetic Biofilm Supports for Treatment Systems.We are currently working on exploring topologies which would be ideal for the growth and support of biofilm. The objective of this work is to produce the results of a series of experimental tests which include a broad variety of architectures ultimately leading to understanding the behavior of biofilms using the new architected lattice metamaterials as a supporting structure for use in treatment infrastructure.

As of now, architected metamaterials have been researched for applications including energy storage devices, biomedical devices, space travel devices, personnel protection and lightweight thermal insulation. Macroscale engineering applications in the literature have been very limited, if any. My research goals aim at identifying applications of architected nano- and micro-lattice architected metamaterials for engineering structures.
