Our research integrates a scientific approach to understanding biological mechanisms with an engineering approach aimed at creating new materials, devices, and systems.
In developmental mechanics, we investigate how form emerges in plant organs through numerical simulations. From zygotes at the µm scale to sepals at the mm scale, we reconstruct plant morphogenesis using continuum mechanics and the finite element method, aiming to elucidate the reciprocal feedback mechanisms between molecular processes and morphology.
In structural mechanics, we investigate how plants use their mechanical properties to support their form. In particular, using elasticity theory, we examine how the stiffness and geometry of plants generate mechanical advantages, and seek to understand the remarkable mechanical efficiency underlying plant structures.
In functional mechanics, we investigate how plants generate forces and apply these mechanisms to the development of actuators. Using soft materials such as silicone gels, we control pressure and anisotropic deformation to elucidate the mechanical conditions that generate flexibility and force.
In movement mechanics, we use data to understand how forces are harnessed to generate movement and conduct research in soft robotics that applies these principles of plant movement. We investigate how forces generated by plants are converted into large deformations and rapid movements. Inspired by the rapid motion of plants such as the Venus flytrap, we propose dynamic surface designs that amplify small stimuli or forces into large deformations, and challenge the development of novel soft actuators and robots.
