About

Our research group is located in the Mechanical Engineering Department at Virginia Tech. We foster an interdisciplinary research environment where scientists and engineers explore fundamental and applied aspects of soft materials. The Soft Materials and Structures Lab is located in the Corporate Research Center and in Goodwin Hall in Blacksburg, Virginia.

Research Focus

Our research lies at the intersection of soft materials, mechanics, and functionality. Through precise experiments and analyses, we study and exploit the fascinating interplay between material composition, geometry, and programmed deformations. This interdisciplinary and biomimetic approach aims to create advanced, multifunctional materials with novel combinations of mechanical and functional properties, including switchable and intelligent adhesives, stretchable electronics and soft robotics, and adaptive and morphing materials.
