Our research is inspired by the interactions of metal ions in natural systems. We focus on the fundamental photochemistry of metal-coordination interactions in polymers and are also interested in understanding how the photochemical reactions of contribute to metal ion cycling in the watershed. In addition, we use this photochemistry as inspiration, creating new photo-responsive materials. We use coordination complexes, biopolymers, and nanoparticles to design the photo-responsive materials. We have designed photoresponsive materials for wastewater treatment and sustainable bioplastics, and are investigating how the metal ion coordination affects degradation and mechanical properties of the materials. We are also interested in how these biodegradable materials can influence nutrient cycling, plant growth, and microbial communities at the agricultural/watershed interface, particularly in coastal systems like the Great Lakes.
Topics of interest:
photochemistry, materials science, coordination chemistry, polymer synthesis, metals in biology, nanoparticle assembly, biomaterials
