Research Interests
Our research program focuses on fabrication, rheology and processing behavior of novel and complex materials.
Various classes of polymeric, soft-solids, gels, colloidal, nanoparticulate and biological systems are of interest to
us. We are also engaged in engineering and characterizing functional fibers, from macro to electrospun
nanofibers. 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. Within this context, recent and/or
ongoing projects in our group include:
•

Synthesis and characterization of nanocomposite polymer electrolytes
Rheology/interactions of self-assembled associative polymers with surfactants and cyclodextrins
Depolymerization of polyethylene terepthalate using supercritical carbon dioxide
