The use of flexible structures and unsteady fluid phenomena – historically avoided in engineering – enhances the performance of many biological mechanisms. Inspired by nature, we aim to leverage these characteristics to advance technologies in a variety of fields, including robotics, energy harvesting and heat transfer. Our group uses experiments and theory to study the complex mechanics that arise when flexible structures interact with a flow. We take advantage of data-driven methods to tackle the large parametric spaces associated with fluid-structure interaction problems.
