The scientific impact maven John Ioannidis from Stanford University and his team have just published a massive ranking of the world’s most-cited authors across all scientific fields in a PLoS Biology paper titled A standardized citation metrics author database annotated for scientific field.

The Ioannidis group used Scopus to analyse the output and citations of 6,880,389 authors who had published at least 5 papers during the 22 years Jan 1996-Dec 31 2017, the latest date when full data were available. In this paper they report on the top 100,000 of these 6.88 million authors (in fact on 105,026). Two searchable supplementary excel tables can be downloaded, one for all 22 years and the other for the single year of 2017.

They ranked the top 105,026 authors across all scientific fields “based on their ranking of a composite indicator that considers six citation metrics (total citations; Hirsch h-index; co-authorship adjusted Schreiberhm-index; number of citations to papers as single author; number of citations to papers as single or first author; and number of citations to papers as single, first, or last author).” The authors argue that this database “provides a measure of long-term performance [and] also reflects their career-long impact or is a very good approximation thereof.”

I spent a couple of hours searching for authors whom I know have made substantial research contributions in the tobacco control field.

The list below shows 86 names that I found in the list of the highest ranked 105,026 authors. Some of these published almost exclusively in the tobacco field, while others published more widely, including in the tobacco area (these I have italicised below).

If you know of others, please let me know via the comment button on this blog and I’ll add their names till we get to the 100 highest ranked.

Several things stand out for me:

  • huge male dominance (just 13 of the 86 are women)
  • a near total dominance of anglophone authors (52 USA, 14 UK, 8 Australia, 5 New Zealand)
  • most of those on the list are older authors, reflecting their outputs across  22 years
  • several are deceased

Many highly productive and influential authors I looked for were not shown in the 105,206 highest ranked. Many of these are younger peoplewho have been publishing for fewer years. One, Geoff Fong from the University of Waterloo in Canada, was not on the list which stunned me. Geoff’s work has had 30,794 cites and he has an H index of 83. I find it incredible that such an output would not catapult him high in any world ranking, yet his name does not appear.
