Assistant Professor
Department of Mechanical Engineering

My research focuses on the mechanics of lattice materials, with the objective of creating new materials by design.  Lattice materials are interconnected arrays of trusses or plates, such as honeycombs, and can be made from any existing solid.  By choosing their topology and parent material, we can design new materials with specific, and often unique, combinations of properties.  My work combines analytical, numerical and experimental methods to provide a better understanding of the mechanical behavior of these lattice materials.
