Supramolecular Interfacial Photochemistry & Nanobiophotonics

My groups research interests lies at the interface of inorganic chemistry, biology and spectroscopy and include projects in the following areas:

• Photochemistry and spectroscopy, in particular, electronic, Raman, and time-resolved spectroscopies applied to the study of Electron and Energy Transfers in supramolecular and heterogeneous assemblies.
• Supramolecular interfacial chemistry; development of photoactive arrays which incorporate controlled degrees of inter-component, and interfacial communication for solar energy conversion and nanoelectronic devices.
• Luminescent polymers and wires for electrochromics and electrochemiluminescence.
• Nanoscale Interfacial platforms for surface enhanced bio-Raman spectroscopy and enhanced luminescence.
• Luminescent probes for heterogeneous microenvironments and biomaterials and cellular imaging.
