Our research is primarily focused on investigating the relationships between structure, thermodynamics, and rheology of soft materials, including self-assembling solutions, colloidal suspensions, and polymeric liquids. A particular focus is to better understand the engineering of fluids which integrate multiple molecular and colloidal components (surfactants, polymers, biomolecules, nanoparticles, emulsions, etc.) to achieve specific stability, rheology, and transport properties. These materials exhibit intimate coupling between structure, dynamics, and flow across the molecular, colloidal, and macroscopic scales which is critical to their processing and performance. To study these phenomena, we are developing multi-scale experimental and theoretical tools in order to: (i) describe molecular and colloidal scale interactions; (ii) characterize mesoscale structure and dynamics, both at equilibrium and under flow; (iii) formulate predictive thermodynamic and rheological models; (iv) design novel materials and processes toward emerging technologies.
Current specific research interests include:
Self-assembling nanoemulsions for smart materials and pharmaceuticals
Mechanical and transport properties of soft nanocomposites gels
Rheological instabilities in surfactants and polymeric liquids
Stability of colloids and biomolecules in self-assembling media
