How can we programme a structure’s behaviour through the way it is cut, connected, and allowed to move?
My research focuses on the inverse design and mechanical behaviour of architected structures, particularly shape-morphing kirigami. I combine geometric optimisation, analytical models, finite element simulations, and physical experiments to connect the design of a cut pattern with the response of a real structure.
A central challenge is the gap between geometric possibility and mechanical behaviour. A pattern may reach a target shape in a kinematic model, yet behave differently under load. I work on methods that account for elasticity and stability as part of the design process.
I am also interested in using elastic instability as a design mechanism: shaping the energy landscape so a structure can move between stable configurations and retain its deployed form. I am now extending this work towards engineering applications, exploring how architected structures can support and reinforce flexible sensors, soft electronics, and metasurfaces through surface-conformal design and controlled deformation.
