The COSMOS lab’s research focus is on developing a framework to discover, design and develop broad classes of advanced materials and structures for a number of mechanical and aerospace systems – specifically soft and collaborative robotic structures, wearable technology, high temperature aerospace structures and inspection technologies.  


To this end, we are especially interested in leveraging the interplay of materials and geometry to obtain unprecedented combinations of mechanical properties. This design principle is at the heart of rapidly expanding frontier of metamaterials. A significant focus of our group lies in observing nature and organisms, specifically revealing the fundamentals of its successful strategies and translating them into engineering design.  


Developing new materials have driven much of engineering enterprise. There are two ways to advance the frontier – innovating on (1) matter itself (new materials) or (2) space (topology/architecture). By combining matter with space (architecture) a truly new frontier of materials development emerges. Such architected solids have traditionally proven to be difficult to manufacture due to intricate spatial geometries. However, rapid advances in additive manufacturing (AM) are making these materials increasingly viable. Still, predicting their properties and behavior is extremely challenging. Purely empirical or experiment driven enterprise is futile due to intractable complexity. Anticipating this issue, our team develops a program of integrated observational, multiscale/multiphysics modeling and experimental platform. The modeling tools are based on the rigorous principles of continuum mechanics and continuum thermodynamics. The computational tools developed for specific problems are based on nonlinear finite element (FE) methods, boundary element methods (BEM), numerical linear algebra and high performance computing. Experimental investigation is carried out using material testing and 3D digital image correlations (3D-DIC).  


We are always looking for highly motivated, creative and mathematically strong students to pursue research in our group. If you are interested in undergraduate or graduate research opportunities, drop an email to the lab director.  Postdoc positions, when available will be posted separately.
