THOMSON SCIENTIFIC NAMES DOCTORS OF THE DECADE, 1995-2005

Harvard University researchers dominate the list of highly cited clinical medicine researchers; University of Miami, Johns Hopkins University also make strong showings.

Philadelphia, Pa. USA-London UK — January 12, 2006 — Researchers from Harvard University lead the pack in clinical medicine research by earning the highest number of citations over the past decade, according to a study published in the January/February issue of Science Watch—the bi monthly newsletter published by Thomson Scientific, a business of The Thomson Corporation.

Using data from Essential Science Indicators SM , the Science Watch study evaluated institutions based on papers published and cited in clinical-medicine journals indexed by Thomson Scientific (including multidisciplinary journals such as Science and Nature).

Harvard University researchers account for four of the top-10 clinical medicine researchers (eight of the top 20), with Meir J. Stampfer receiving the highest number of citations, 34,872, for his work in the field of Epidemiology. Another Harvard researcher, Walter C. Willett, ranks a close second with 33,724, while University of Miami researcher Charles H. Hennekens ranks third with 27,629 citations. Willett and Hennekens also published in the field of Epidemiology.

Rounding out the top five are Bert Vogelstein of Howard Hughes Medical Institute and Johns Hopkins University with 27,148 citations, and Kenneth W. Kinzler, also of Johns Hopkins, with 25,785. Both researchers published in the field of Oncology.

“Citations are an acknowledgement of intellectual debt,” said Christopher King, editor of Science Watch. “The impressive number of citations these exceptional researchers have received is evidence of their profound influence on modern scientific thought.”
