My research interests focus on the rheology of structured polymeric systems, particularly the relationship between material microstructure, chemistry, and macroscopic properties. The use of rheology with other techniques provides a powerful and unique combination to understand and describe the macroscopic behavior of structured systems in terms of their underlying chemistry and/or microstructure. My goals have been to use such an approach to obtain physical insights and new information on systems that are technologically or environmentally relevant. Summaries of some of the group research projects are provided below.
