How does a dense suspension know it is about to fail?
We study the non-equilibrium dynamics of soft matter — colloidal suspensions, vitrimer nanocomposites, and battery electrode slurries — using in situ Rheo-SAXS-XPCS at the Advanced Photon Source. By tracking structure and motion from the nanoscale up, we build constitutive models and machine-learning tools that connect molecular rearrangements to macroscopic rheological transitions.
Research Areas
Adaptive Nanocomposites
Vitrimers and nanofiller networks with reversible bonds that self-heal, reconfigure under load, and maintain conductivity across thousands of cycles — targeting soft robotics, flexible electronics, and energy storage.
Non-Equilibrium Physics
Real-time Rheo-SAXS-XPCS at the upgraded APS captures how network topology, cooperative particle motion, and shear banding evolve during deformation in dense soft matter.
Sustainable Biocomposites
Solvent-free dynamic covalent networks from polyhydroxyalkanoates and polysaccharides that extend food shelf life while replacing petroleum-based packaging films.
