Our research is focused on the molecular design of nanostructured polymer systems and biomaterials to precisely control molecular architecture and functionality in these systems. The overall goal is to answer critical questions related to organization and dynamics occurring on length scales ranging from the nanometer to the micron-scale at surfaces of and interfaces between polymers, inorganic materials (e.g., magnetite nanocrystals), cells, and biomolecules (e.g., proteins). Our research directions can be classified into two broad themes: nanostructured polymers, nanoparticles, and nanocomposites; and engineered biomaterials for drug delivery and tissue engineering. The tools that we utilize include novel synthesis methodologies, state-of-the-art characterization of nanostructure and dynamics, and molecular modeling.
