El Gamal, Shroff noted for citations

Professors Hesham El Gamal and Ness Shroff were included in the new list for their work in computer science. Thomson Reuters says its selection of influential researchers was based on total citations gives preference to well-established scientists and social sciences researchers who have produced many publications.

The old list, first issued in 2001, identified more than 7,000 researchers -- including two from the department, Robert Lee and John Volakis -- who were the most cited in computer science at the time. The 2001 analysis considered articles and reviews published in Web of Science-indexed journals from 1981 through 1999. Approximately 250 researchers in each field were selected based on total citations to their papers published during this period.

Thomson Reuters focused on more contemporary research achievement. Only articles and reviews in science and social sciences journals indexed in the Web of Science Core Collection during the 11-year period 2002-2012 were surveyed.

Rather than using total citations as a measure of influence, only highly cited papers were considered.Those papers are defined as those that rank in the top 1 percent by citations for field and year indexed in the Web of Science, which is generally but not always year of publication.
