Photochemistry/Spectroscopy and Dynamics/Structural Biology

Describing electron- and energy-transfer processes in nanoscale systems is critical not only for understanding fundamental energy redistribution mechanisms in nanoscopic media, but also for developing next-generation devices based on these technologies. Research in the Knappenberger group involves understanding these processes in nanoscale assemblies through development and implementation of novel optical spectroscopy techniques, including single-molecule and time-resolved methods. The resulting detailed chemical information will address critical issues in nanoscale chemical physics and single-molecule analytical chemistry and direct the assembly of carefully designed nanoscale architectures.
