Research interests revolve around the modeling and simulation of complex wave phenomena in unconventional structures and materials, with emphasis on cellular solids, phononic crystals and acoustic metamaterials. Current efforts are directed towards the investigation of wave motion in nonlinear periodic solids, such as granular crystals, with the objective of designing strategies for tunable filtering and wave steering. In parallel, new theoretical and experimental techniques for material diagnostics and structural health monitoring are developed through the structural mechanics adaptation of selected ideas originated in the fields of machine learning and computer vision.
