The list of most cited researchers in 2025 was published; Iran 3 – Saudi Arabia 30 – Mehr news agency RCO News Agency

According to the reporter of Mehr, in recent days, the list of “most cited researchers” in the world in 2025 by Institute Clarivit Analytics (formerly ISI) was published. This list is published annually since 2014 and the researchers who influence It introduces significant and extensive in their research fields.

In the latest list of highly cited researchers; 6 thousand 868 people have been introduced in different scientific fields.

The following table shows the number of highly cited researchers in different scientific fields. Some people in several different scientific fields have been introduced as highly cited researchers.

Researchers highly cited This year, they are from 60 different countries and regions. However, 86.1% of them belong to only 10 countries and regions, and 74.6% of them are concentrated in only 5 countries.

With 2,670 highly cited researchers in 2025, America has the highest number of highly cited researchers in the world. This figure is equivalent to 37.4% of all the most cited researchers in the world.

America’s share of the world’s most cited researchers in 2025 has increased slightly by one percent. Previously, in the past years, the share of highly cited researchers in the United States was decreasing.

China has maintained its second place this year with 1406 highly cited researchers (19.7% of the world). This represents a small increase in the number of researchers in the world, but a slight decrease of 0.7% in the global share compared to 2024, which was 20.4%. Previously, China’s global share of highly cited researchers was steadily increasing, and China has been able to more than double its share of the population of highly cited researchers since 2018.

With 570 highly cited researchers (8% of the world’s most cited researchers), England is again ranked third this year, followed by Germany (363), Australia (312), Canada (227), the Netherlands (194), Hong Kong (145), Switzerland (130) and France (121). Switzerland is back in the top 10 this year, while Singapore, which was ranked 10th last year, has fallen from this ranking. Also, France has been promoted from ninth to tenth place.

in between Institutions In the world science, in 2025, the Chinese Academy of Sciences ranks first with 258 highly cited researchers, followed by Harvard University (170), Stanford University (141) and Chinhua (91) are located. Among the other universities in the top 10 universities, MIT University (ranked 85) has been promoted from the sixth place last year to the fifth place. Institute The National Health Service of America has taken (84). The University of Oxford (59), University College London (59), the University of Pennsylvania (59) and the Max Planck Society still rank highly. Institute Max Planck in terms of the number of researchers highly cited (from 56 researchers in 2024 to 66 researchers) and has increased from the ninth to the seventh rank.

The number of highly cited researchers in Iran remained 3

In 1400, Iran had the largest number of highly cited researchers, and in the last 4 years, this amount has decreased by more than 80%. Last year, the number of Iran’s most cited researchers reached the lowest number since the beginning of the list (2014), and this year, Iran’s most cited researchers remained three.

Mehdi Dehghan in the field of mathematics (professor of the Faculty of Mathematics and Computer Science of Amirkabir University of Technology), Mohammad Ali Mansournia In the field of social sciences (Professor Epidemiology and Biostatistics of Tehran University of Medical Sciences) and Majid Soltani in the interdisciplinary field (Associate Professor of the Department of Transformation Bio-energy Khwaja Nasiruddin Tosi University of Technology) are the only highly cited researchers of Iran in this prestigious list.

In the list of most cited researchers in 2025, Saudi Arabia has 30 highly cited researchers and Türkiye has 2 highly cited researchers.

There are many references about highly cited Saudi researchers. Between 2014 and 2022, the number of people who were in the list of highly cited researchers with Saudi organizational affiliation increased from 29 people to 109 people, but since two years ago, the trend of these researchers in Saudi Arabia has also decreased.

Saudi Arabia has sought to attract the best researchers in the world for more than a decade. This country invites top researchers to work in the institutions of this country and hold courses in these institutions, study opportunities let themto teach as visiting professors, and in return, Saudi Arabia provides them with financial and laboratory facilities. It is also said that Saudi Arabia offers very high amounts of money to hire these researchers.

Following the protests of the universities and the reports published by the world’s authoritative media about the recruitment of researchers from other countries by Saudi Arabia, Institute By changing its assessment method, Clarivit introduces people who work in a university in a real way without manipulating their organizational affiliation in the final list of highly cited researchers. Accordingly, it seems that the decrease in the number of highly cited researchers in Saudi Arabia has occurred as a result of these changes.

Removal of 2,400 candidates to maintain the validity of the list of highly cited researchers

Trust in scientific research has faced serious challenges in recent years, and the quality of data and the credibility of researchers highly cited It has become more important. Institute Clarivit to prepare the annual list of researchers highly citeddue to technological advances and changes in scientific publishing, has revised its criteria and policies to make accurate identification of genuine researchers possible.

Accordingly, some key measures include removing articles with more than 30 authors or articles written by people with Sue Known scientific behavior has been published. Also, by removing unusual citation networks, the mathematics branch is back on the list of researchers highly cited The return and diversity of real researchers has increased. Algorithmic and human analysis have also been used for the investigations.

Accordingly, to prepare this list of authors with many articles, people who self-citation severe and have cited too much to close colleagues; have been deleted And as a result of these reforms, about 2,400 people were removed from those who were on the list of candidates for the most cited researchers this year. In 2022, as a result of the reviews, 500 people were removed from this list, and this process has reached the removal of more than 2000 people in 2024. These changes emphasize that accurate and qualitative evaluation of research is necessary along with quantitative data, and the scientific community must maintain the integrity and honesty of research through peer review and adherence to international standards.
