Research Interests

My research interests lie in the field of deployable and reconfigurable structural systems. Folding and adaptable structures based on the principles of origami can have practical applications ranging in scale and discipline from biomedical robotics to deployable architecture.

I am interested in developing analytical tools that can simulate mechanical and multi-physical phenomena of deployable structure, including the analytical codes incorporating folding kinematics along with local and global phenomenological models. My research includes how the geometry affects stiffness and other properties can allow for the optimization and discovery of new deployable structures.

My research also deals with the design and manufacturing of deployable structures using 3D printing and other fabrication techniques. Multi-material additive manufacturing can be used in intermediate scales to create cellular metamaterials with unique and adaptable characteristics (e.g. high stiffness-weight ratios and variable thermal conductivity). I am also exploring large-scale folding systems where thick panels are connected with hinges and are deployed by mechanical devices.
