DURHAM, N.C. – William L. Chameides, dean of 91ÉçÇø¸£Àû’s Nicholas School of the Environment, has been named one of the world’s most highly cited scientists by the international online research database ISI Highly Cited.com.

Inclusion on the list is based on authorship of papers considered by peers to be among the most important scientific developments of the past 25 years. Only the most widely cited authors – less than half of one percent of all published researchers – have earned recognition. Citation is a direct measure of a researcher’s influence on the literature of a subject, and also is a strong indicator of the far-reaching contributions the researcher’s work has made to his field.

Chameides, an atmospheric chemist, was named to the ISI Highly Cited list for geosciences.

His research focuses on the causes of, and remedies for, global, regional, and urban environmental change, and has helped lay the groundwork for modern science’s understanding of the photochemistry of the lower atmosphere, the importance of nitrogen oxides emission controls in the mitigation of urban and regional photochemical smog, and the impact of regional environmental change on global food production.

Chameides has more than 30 years experience in academia as a professor, researcher, teacher, and mentor, with a three-year stint in the NGO world as the chief scientist of the Environmental Defense Fund. He joined Duke as the dean of the Nicholas School in 2007. He is a member of the National Academy of Sciences, a fellow of the American Geophysical Union, and a recipient of the American Geophysical Union’s MacElwane Award.

He blogs about environmental issues, with an emphasis on identifying pathways to a more sustainable future, at , The Huffington Post, and on the website for Scientific American.

Chameides joins five other Nicholas School faculty members previously named to the ISI Highly Cited list: Robert B. Jackson, Nicholas Professor of Global Environmental Change; James S. Clark, H.L. Blomquist Professor of Environment, professor of biology and statistics; Stuart L. Pimm, Doris Duke Professor of Conservation Ecology; Richard T. Barber, Harvey W. Smith Professor Emeritus of Biological Oceanography; and William H. Schlesinger, James B. Duke Professor Emeritus of Biogeochemistry and former dean of the Nicholas School.

More than two dozen members of the 91ÉçÇø¸£Àû faculty are included on the list, which is accessible online at .
