The AD Scientific Index World Scientist and University Rankings 2023 reflect a significant distinction demonstrating the high quality, global impact, and recognition of NKUA’s research work. More specifically, the Institution ranks 92nd globally out of 19,514 Universities from 216 countries included in this ranking. Furthermore, it ranks 25th in Europe and 1st among the other Greek public Universities for 2023 (see Table 1). It should be noted that, as shown in Figure 1, which depicts NKUA’s performance in the individual criteria of the ranking, in the i10 index of the last five years, the Institution ranks 61st globally and 15th in Europe.
AD Scientific Index is the first and only ranking based on the overall and most recent indexes (from the last five years) of research productivity of the Universities’ most influential scientists and researchers. More specifically, each University’s performance, score, and place are calculated based on the h-index, i10 index scores, and the number of citations received by its research staff as reflected in Google Scholar.
The ranking for 2023 takes into account the research work of 1,153,395 scientists from 216 countries, 7,706 of whom are Greek Professors at Greek public Universities.
Another significant distinction for NKUA is that it has the most scientists in this ranking among Greek Universities (1437), with 54 of them ranking in the top 2%, 276 in the top 10%, and 548 in the top 20% of researchers globally (see Table 3).

There are four metrics for countries, the first being the number of scientists from each University on the list of the top 10,000 scientists. The second metric is the number of scientists from each University on the list of the 100,000 scientists with the most significant research production. The third metric is a University’s total number of scientists listed on the AD Scientific Index. In the event of a tie, a fourth metric, namely the highest global ranking among researchers ranked first in their Institution, applies. The overall h-index value, i10 index value, and citation count are used, as well as the h-index value, i10 index value, and citation count from the previous five years. Researchers’ profiles in Google Scholar provide data, and there is a constant update of both the data and the placing of Institutions so that this ranking conveys a dynamic rather than a static picture.

As previously stated, the National and Kapodistrian University of Athens ranks 1st in Greece and 92nd in the world in AD Scientific Index World Scientist and University Rankings 2023, with Aristotle University of Thessaloniki (422nd place worldwide) and the National Technical University of Athens (485th place worldwide) following. The University of Crete (540th place worldwide) and the University of Ioannina (592nd place worldwide) round out the top 5 nationwide.
Harvard University tops the ranking internationally, followed by another American University, namely Stanford. Next comes a British University, the University of Oxford, the only European University in the top 10 of the AD Scientific Index World Scientist and University Rankings 2023.
The results of this ranking highlight the multilevel, extroverted, and, above all, influential research conducted by the NKUA faculty members and researchers. Especially in global rankings, based on open access tools and a variety of criteria that focus on the research impact of the last ten years and emphasize quality rather than quantity in research, it turns out that NKUA is rightly ranked among the top 100 Universities worldwide.
