The data on high-impact researchers in pharmacology and toxicology presented in the table above were extracted from the Essential Science Indicators database of Thomson Reuters. This database surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a field based on the journals in which they were published and a journal-to-field scheme used by Thomson Reuters. Papers in multidisciplinary journals, such as Nature and Science, are selectively assigned to a field based on a paper-by-paper analysis. Both articles tabulated and citation counts to those articles are for the period indicated. Naturally, scientists publishing large numbers of papers have a greater likelihood of collecting more citations than scientists publishing fewer papers. This ranking is by citations per paper to reveal weighted impact. A threshold of 50 papers was employed to identify particularly active scientists. For articles with multiple authors, each author receives full, not fractional, publication and citation credit. ESI lists authors ranked in the top 1 per cent for a field over a given period, based on total citations.
In the current version of ESI, 2,949 authors are listed in the field of pharmacology and toxicology, meaning that approximately 294,900 author records were surveyed to obtain these results. Of the 2,949 authors in the top 1 per cent by citations, 679 published 50 or more papers during the period surveyed. In addition to the number of papers for each researcher, the table also includes, in brackets, the number of top papers each published over the period. Top papers are defined as either highly cited papers or hot papers. Highly cited papers rank in the top 1 per cent by total citations in their field when compared with papers published the same year.
Hot papers are those two years old or younger that rank in the top 0.1 per cent by citations when compared with papers in the same field and those appearing within the same two-month publication window. The average impact for papers published in pharmacology and toxicology journals over the period is 12.0, so all authors listed in the table exhibit citations-per-paper scores more than three times expectation.
