Claudia Turro received her B.S. with Honors in 1987 from Michigan State University. She worked with Daniel G. Nocera and George E. Leroi at Michigan State University and received her Ph.D. in 1992. She was awarded a Jane Coffin Childs Memorial Fund for Medical Research Postdoctoral Fellowship to continue postodoctoral work at Columbia University with Nicholas J. Turro from 1992 to 1995. She has been a faculty member at The Ohio State University since 1996. She received the Early CAREER Award by the National Science Foundation in 1998, the Arnold and Mabel Beckman Foundation Young Investigator Award in 1999, was named a 2010 Fellow of the American Chemical Society, and a 2012 Fellow of the American Association for the Advancement of Science.  She was elected Vice Presdient (2010-12) and President of the Inter-American Photochemical Society (2012-14), and Chair of the Bioninorganic Subdivision of the Division of Inorganic Chemistry of the American Chemical Society (2013-14). She received the College of Arts and Sciences inaugural Susan M. Hartmann Mentoring and Leadership Award (2014) and the 2014 Inter-American Photochemical Society Award in Photochemistry.

Research Overview

Inorganic Photochemistry, Excited State Processes, Control of Charge Separation and Recombination, Solar Energy Conversion

The Turro group is interested in understanding and utilizing reactions of metal complexes that can be initiated with light. The potential applications of these reactions span the areas of photodynamic therapy (PDT) for the treatment of tumors, luminescent reporters and sensors, degradation of pollutants triggered by light, and solar energy conversion. In order to improve and expand their reactivity, the fundamental understanding of the excited states of mononuclear and dinuclear metal-metal bonded transition metal complexes is necessary and remains an important subject of investigation. This work is currently funded by the National Science Foundation. The work in the Turro group continues to address long-range charge transport, as well as the chemical control of charge separation and charge recombination. Understanding and controlling these processes is vital for efficient solar energy conversion. Transition metal complexes that are nontoxic in the dark and become highly toxic upon irradiation with visible or near-IR light are ideal for PDT. Complexes that undergo photo-induced ligand-loss are under investigation, such that the complex can covalently bind to DNA following photolysis and disrupt cellular processes in a manner similar to cisplatin, while simultaneously releasing drugs. This work is currently supported by the National Institutes of Health.  The Turro group has also discovered new materials that are able to both harvest photons and undergo catalytic transformations to prodcuce clean fuels.  This work is currently funded by the Department of Energy.
