I have over seventeen years of experience doing basic and applied research on polymer materials, including melts, blends, solutions and films. Since 2001 I have worked on the interaction of polymers and biological polymers with organic nanoparticles, including the processing of polymer composites and single-wall carbon nanotubes coated with biological materials. I work at the leading edge of research on polymer characterization and have collaborated with industry to solve an array of problems in rheology and polymer processing.Recent projects include:• Synthesis and characterization of transparent polymer films of aligned single-wall carbon nanotubes stabilized using biological polymers• Interactions between cells and single-wall carbon nanotubes wrapped with biological polymers• Length dependent characterization of single-wall carbon nanotubes coated with biological polymers• Development of optical methods to measure the interface between soft polymer materials and flowing viscous fluids• Measuring the effect of dispersive polymer coatings on charge transport in polymer nanocomposites• Structure-property characterization of polymer composites containing single-wall carbon nanotubes wrapped with biological polymers• Synthesis and characterization of cross-linked polymer colloids stabilized by single-wall carbon nanotubes coated with biological polymers• Structure-property characterization of lipid mixtures and bile-acid solutions• Structure-property characterization and flow processing of polymer blends and nanocomposites• Phase separation and dewetting in polymer films• Colloidal interactions and stability• Particle-tracking measurements of polymer gel dynamics• Nanosecond pulsed-laser measurements of thermal boundary resistance between thin polymer films and silicon wafers• Polymer processing optical visualization schemesSpecialties: nanotechnology, biotechnology, polymer processing, rheology, optics
