Active Molecular Plasmonics: Applications and Fundamentals of SERS

My research activities encompass the fundamentals and applications of active molecular plasmonics using functional chromophores. Developing new methods for interfacing functional molecules with reproducible nanostructures that support tunable plasmons paves the way for information processing and sensing. I use surface-enhanced resonance Raman scattering (SERRS), along with a host of other analytical techniques, to address the fundamental questions of how chromophores and plasmons interact. I collaborate within an international team of researchers, and together we are harnessing synthesis, spectroscopy and theory in pursuit of answering the most fundamental questions surrounding surface enhancement effects and addressing the challenges of transferring plasmonics sensing technology from the laboratory to the field.
