Our research approach emphasizes the use of mathematical modeling to understand and quantify the underlying physics that govern the assembly, properties, and responsive nature of our materials. Using this strategy, we have developed a physical and quantitative understanding of polymer-nanoparticle (PNP) hydrogel assembly (Nature Communications 2015). We have additionally developed statistical-kinetic models to describe and predict how material properties change within photoresponsive hydrogels in response to controlled light exposure (Macromolecules 2013; Journal of Polymer Science Part A 2013).
