Our research program focuses on the rheology and processing behavior of novel and complex materials. Various classes of polymeric, colloidal, nanoparticulate and biological systems are of interest to us, particularly those relevant environmentally, biochemically or as advanced materials. Our work, by nature, tends to be inter-disciplinary with strong collaboration both within and outside the university. A common binding thread in our work is the emphasis on unearthing relationships between material micro/molecular structure, chemistry, and macroscopic properties. Typically, we use rheology in conjunction with other characterization techniques that includes Small Angle Light Scattering (SALS), Gel Permeation Chromatography (GPC) and Laser Scanning Confocal Microscopy (LSCM). While we have used such a multi-prong approach to address the major projects listed below, we have also ventured into other territories that include drug delivery and diffusion in hydrogels, gelation of cellulosic materials, formation of protein gels, and nanocomposite single ion conductors
