Research Interests

Our mission in the Soft Matter Mechanics Lab is to (1) understand mechanics in soft materials, (2) identify the theoretical limits of the mechanical properties, and (3) design the molecular structure to approach the limit. A deeper understanding of soft materials with extraordinary material properties will innovate diverse fields such as polymer pollution, robotics, human-machine interfaces, and biomedical devices.
