Research Interest

I am engaged in understanding polymer structure and dynamics in solutions, gels and elastomers. We employ a combination of scattering techniques (neutron, X-ary and light) and rheological measurements to reveal the underlying mechanism between nanostructures and macroscopic mechanical response.
