Research Interests

Experimental Synthesis & Reactions
  • Control of colloidal morphology in polymeric nanoparticle synthesis (encapsulation, multi-component structured latex, hollow latex, hybrid (alkyd/acrylic, PU/acrylic) latex, etc.)
  • Colloids derived from sustainable starting materials
  • Stimuli-responsive coatings and composites (e.g. self-healing coatings)
  • Molecular and macromolecular architecture control by living free-radical polymerization

  • Modeling
  • Dynamic modeling of colloidal interactions, film formation, & evolution of multi-phase morphology
  • Dynamic modeling of reaction kinetics, phase separation, and particle morphology development
  • Hydroplasticization of copolymers and impact on diffusion, phase separation, and viscoelastic properties
  • Distribution of water within polymer colloids
