Rodney J. Bartlett, the Graduate Research Professor at the Quantum Theory Project, University of Florida, pioneered the development of coupled cluster (CC) theory in quantum chemistry to offer highly accurate solutions of the Schrodinger equation for molecular structure and spectra. He is a Fellow of the International Academy of Quantum Molecular Sciences (1991), the American Physical Society (1986), and the Guggenheim Foundation (1986). He has published over 500 papers and book chapters, presented over 200 invited lectures at major meetings, and received numerous awards.
