About the Research

Research Theme

Exploring the mechanisms of chemical reactions in soft materials


Polymer gels, Functional materials, Fracture mechanisms

Research Outline

Before joining ICReDD, I focused on the fracture mechanisms of soft and tough double network (DN) materials mainly from the perspective of polymer physics and fracture mechanics. Now one of my research interests is to understand the mechanisms of special chemical reactions in gel materials combining computational and experimental results.
