Assessment criteria includes researchers’ academic production
Seven PUCRS professors have been ranked among the most influential researchers in the world according to a database created by Journal Plos Biology. The study carried out at Stanford University, in the US, is published every year and assesses researchers in two different perspectives: one assessing scientists for career-long citation impact (Table-S6-career-2019) and another assessing scientists for single-year impact up until the end of 2019 (Table-S7-singleyr-2019).
In the list of the most influential researchers for career-long citation impact, four PUCRS researchers made it to the list, as follows: André Palmini (School of Medicine), Ivan Izquierdo (School of Medicine), Roberto Esser Reis (School of Health and Life Sciences) and Walter Filgueira de Azevedo (School of Health and Life Sciences). On the other hand, the list of most influential researchers in 2019, includes the following researchers: Ivan Izquierdo, Maria Martha Campos (School of Health and Life Sciences), Moisés Bauer (School of Health and Life Sciences), Renato Tetelbom Stein (School of Medicine), Roberto Esser Reis and Walter Filgueira de Azevedo.
The database lists the 100,000 most influential scientists in the world, according to the composite citation index and other criteria. In addition, the list also includes scientists who are not in the top 100,000 according to the composite index but are nevertheless within the top 2% of scientists of their main subfield discipline.
According to the database, citation metrics are widely used, but not always correctly. For this reason, Plos Biology created a publicly available database that features the 100,000 leading scientists on the planet, considering standardized information on citations, h index, multi-author hm index, citations of articles in different authoring positions and a composite indicator. In this database, the separate data is shown for impact throughout the career and single year.
Also according to the document, “metrics are provided with and without self-citations and proportion of citations for cited articles. Scientists are classified into 22 scientific fields and 176 subfields. Field and subfield specific percentiles are also provided for all scientists who have published at least five articles. The data for career-long citation impact will be updated by the end of 2019 “.
