Charged soft matter systems, such as polyelectrolytes, complex coacervates, colloidal suspensions, and soft gels, exhibit rich structural and dynamical behavior arising from the interplay between electrostatic interactions, confinement, and viscoelasticity. Our research focuses on understanding how charge, architecture, and external flow fields control the rheological and structural response of these materials across multiple length scales. By combining rheology with scattering techniques and advanced material characterization, we aim to establish design principles for soft charged materials with tunable mechanical and transport properties.
