Research

Our research focuses on the synthesis of polymer semiconductors and polymer nanomaterials. We target polymers with optical and electronic properties that make them well suited for solar energy, sensing, and biomedical imaging. The chemical challenge is that polymer properties are controlled by both molecular structure and interactions beyond the molecular scale. Our approach is to design and synthesize novel polymers, control the organization of these polymers at the nanoscale, and determine how structure and interactions influence properties. If you are interested in learning more about the research projects, or you would like to join our team, please contact me.
