 | Areas of Research Interest: Self-assembly and biomacromolecules. In the area of self-assembly, weak forces are used to control both the equilibrium phase behavior as well as the kinetics of assembly. Hydrophobically modified polymers interact with surfactant mesophases, lipid bilayer surfaces, colloids, or other amphiphilic polymers in aqeuous solution. Competitive kinetics of nanoparticle formation and block copolymer assembly can be tuned to create stable nano-particles for drug therapy. Self assembly in non-aqueous solutions can be driven by crystallization. The kinetics of self-assembly of block copolymers and wax crystals can be used to stabilize diesel fuels and crude oil against gelation. In these areas we use combinations of optical, rheological and scattering techniques to relate structure to properties. In the second area of biopolymers we work to understand how nature uses weak hydrogen bonding forces to tailor interactions between biomacromolecules. These forces determine polymer solubility and rheology. New techniques such as fluorescence probe photobleaching and osmotic stress diffraction allow us to probe molecular level interactions.
