Graham Fleming

Graham R. Fleming is a professor of chemistry at the University of California, Berkeley and member of the Kavli Energy NanoScience Institute based at UCB.^[1][2]

Fleming's team is known for developing and using techniques in advanced multidimensional, ultrafast spectroscopy to study complex condensed phase dynamics in systems including natural photosynthetic complexes and nanoscale systems including single-walled carbon nanotubes^[3][4] and organic photovoltaic systems.^[2]

These investigations and the findings of Fleming's team have indicated the key role of quantum electronic coherence in disordered biological environments. These findings have pointed towards the importance of examining the role of quantum dynamical processes in biological energy harvesting systems.

Education, career, and service

Fleming was born 3 December 1949 in Barrow (now Barrow-in-Furness), England, and received his B.S. degree with honors in chemistry from the University of Bristol in 1971. He subsequently received his Ph.D. in physical chemistry from the University College London and the Royal Institution in 1974. Fleming then held postdoctoral researcher appointments at three institutions: California Institute of Technology (1974–1975); University of Melbourne (1975–1976); and the Royal Institution (1976–1979).

In 1979, Fleming began his independent research team with a faculty appointment at the University of Chicago. He was promoted to associate professor at the University of Chicago in 1983 and in 1985 was made a full professor. In 1987, Fleming was named the Arthur Holly Compton Distinguished Services Professor a position which he held for ten years. At the University of Chicago, Fleming served for three years as the chair of the chemistry department. During his time at the University of Chicago, he worked with John Keith Moffat to found the University's first new research institute in 50 years, the Institute for Biophysical Dynamics.^[5]

Fleming transitioned his research team to the

In the areas of service to the university, Fleming also served as the vice-chancellor for research at UCB from April 2009 to 2015.^[6]

Harassment allegations

Fleming resigned from his position as vice chancellor for research (2015) and was subsequently removed as a Berkeley Global Campus ambassador (2016) following the filing of a harassment complaint against him by a former employee in 2014. The investigation that followed determined Fleming had violated the University of California's sexual harassment policy.^[7]
