Brazil reduces from 18 to 14 names on the list of the world’s 6,600 most influential scientists; see who they are .      Most of the researchers are from USP and are part of a core group in the field of health and nutrition Brazil has secured the inclusion of 14 scientists in this year's edition of the list compiled by British consultancy Clarivate Analytics, which has identified the world's most influential figures based on citations of their academic articles since 2014. The country has seen a decrease in its representation, having had 18 names on the list last year. The total list, released this week, features 6,636 names from 1,200 institutions, highlighting the top 0.1% of scientists based on this citation-based criterion.

Brazil has secured the inclusion of 14 scientists in this year's edition of the list compiled by British consultancy Clarivate Analytics, which has identified the world's most influential figures based on citations of their academic articles since 2014. The country has seen a decrease in its representation, having had 18 names on the list last year. The total list, released this week, features 6,636 names from 1,200 institutions, highlighting the top 0.1% of scientists based on this citation-based criterion.

Among the Brazilian researchers, six are from the University of São Paulo (USP), with five belonging to the Center for Epidemiological Research in Nutrition and Health (Nupens). The high number is partly due to the collaborative nature of Nupens' work, where the success of one researcher often boosts the citations of the entire group (see the full list below).

Led by public health expert Carlos Augusto Monteiro, much of the group's influence stems from their research on the health impacts of processed foods. Monteiro and his colleagues are credited with coining the term "ultra-processed foods" to describe heavily industrialized products with ingredients unfamiliar in home cooking.

Almost all Brazilian researchers on the Clarivate list work in the biological sciences, with some overlapping into the humanities. Only one, Peruvian physicist and climatologist Jose Marengo from the National Center for Monitoring and Alerting of Natural Disasters (Cemaden), is from the exact sciences.

Not all scientists on the list are Brazilian nationals, but all are affiliated with Brazilian institutions. Clarivate's criterion for selection is the location of the research center where the individual works. Observers might find some notable researchers absent from the list, but this is not unusual given the dynamics of scientific production.

— Those listed by Clarivate are mainly scientists working on global issues, such as climate change — explains Sabine Righetti, a researcher at Unicamp specializing in scientific production indicators. — Nupens researchers fit this category as the study of obesity with a focus on nutrition is increasingly a global scientific priority.

According to Righetti, while lists like Clarivate's and other academic rankings are significant, the metrics for evaluating researcher influence are starting to incorporate other criteria.

— Even Capes is changing how it evaluates researchers, aiming to consider the social impact of research — she notes. — An example includes studies influencing changes in regulations, legislation, and decision-making documents. Some international consultancies are beginning to follow this approach as well. Sometimes a highly cited scientist may have less social impact, and vice versa.

Clarivate's ranking criteria involve the citation of academic articles in a large scientific literature database, with qualitative analysis and expert judgment also playing a role in creating the list.
