Our group utilizes both experimental and theoretical methods to research fundamental aspects of organic photochemistry. Our main focus is controlling and amplifying the production of reactive oxygen species. Our current projects involve organic oxidation mechanisms, visible-light photosensitization, reactive intermediates, and photo-reactor development. One research area deals in the pioneering use of fiber optics combined with sensitizer drugs for the production and precise delivery of singlet oxygen to eradicate cancer cells. We also study the interfacial behavior of reactive oxygen species, including the localized delivery of singlet oxygen and alkoxy radicals both as individual or tandem disinfectants. We probe our reaction mechanisms using density functional theory for theoretical calculations which guide and deepen our understanding of experiments. Our work is currently funded by the National Science Foundation.
