Overview of Research
We are engaged in understanding the polymer structure and dynamics of soft materials, including polymer solutions, gels, elastomers, micelles, colloids, and cells. We employ a combination of scattering techniques (neutron, X-ray, and light), rheological measurements, and spectroscopy to reveal the underlying mechanism between nanostructures and physical properties. We also develop new high-performance soft materials using the revealed mechanism from the structure analysis.
