Research Interests
Almost all of my research concerns surfactants and colloid science; much of it is directly related to applications. I am very interested in seeing people use what I have discovered or developed. Consequently, the importance of surfactants and colloid science in many different industrial applications involves me in a variety of technologies.
My research ranges from applied areas such as environmental remediation (in-situ ground water remediation) or polymer composites (modification fillers and reinforcers by admicellar polymerization), to basic areas such as microemulsion theory and surfactant precipitation, which support the large number of industries that utilize surfactants. Applications of my research range from remediation of ground water contaminated by fuels or solvents, to novel materials for new tire treads, to improved cleaning formulations. All of these topics are connected through the importance of surfactants in controlling interfacial properties in engineering systems.
Recently I have found myself being drawn into nanotechnology research, especially in the area of fullerene nanotubes and nanotube reinforced composites. Surfactants will play critical roles in the evolution of this technology, from catalyst preparation, to dispersal of nanotubes in a matrix, to development of the separations processes required to produce commercial quantities of fullerene nanotubes.
