The study by John Ioannidis of Stanford University, Kevin Boyack and Jeroen Baas, which collects 2% of the most cited researchers in the world, was recently published in the international journal Plos Biology. It is a bibliometry study that analyzes the impact and distribution of scientific publications within the academic community.

The study is based on data obtained in May 2020 from the Scopus scientific research database, data then updated with the standardized citation indicators for the year 2019, comparing the scientific production of about 8 million researchers from universities and research centers. research from around the world, in 22 scientific fields and 176 subfields.

For each researcher, the sector in which he is active is indicated and the corresponding ranking, differentiated between rankings that include self-citation references and those that do not include them.

The list drawn up by Stanford University includes 9 researchers from the University of Sannio. The 'Top Scientists', as defined by the journal Plos Biology, are: Gerardo Canfora (Software Engineering); Giuseppe Graziano (Chemical Physics); Massimiliano Di Penta (Software Engineering); Fernando Goglia (Biochemistry and Molecular Biology); Andrea Cusano (Optoelectronics & Photonics); Pasquale Daponte (Electrical & Electronic Engineering); Antonello Cutolo (Optoelectronics & Photonics) Maria Rosaria Pecce (Civil Engineering); Sergio Rapuano (Electrical & Electronic Engineering).

The same magazine also publishes the top scientists with reference only to the year 2019, which represents an important indication also on "young" researchers. Here appear for UniSannio: Gerardo Canfora, Marco Consales, Andrea Cusano, Pasquale Daponte, Luca De Vito, Massimiliano Di Penta, Francesco Fiorillo, Giuseppe Graziano, Francesco Lamonaca, Maria Rosaria Pecce, Alfredo Vaccaro.
