Bertoldi Group

Welcome

Welcome to the Bertoldi Group at Harvard University. In our research, we combine theoretical, computational and experimental methods to gain deeper insight into the non-linear behavior of materials and structures. Guided by theoretical and numerical analysis, we exploit material and geometric non-linearities to design novel materials with tunable exceptional properties, and we seek to create and test such materials. Read more about some of our recent and ongoing research projects in the Research section.
