In terms of scientific dissemination, in 2025 the University of Valencia published 7,126 articles, 237 books and 1,873 book chapters, and made 385 conference contributions, in addition to 461 participations in reviews, letters, working papers, notes, brief studies, data articles, reports, dictionary entries, etc.
Over the course of the calendar year, 166 doctoral theses were defended (173 supervised theses are registered), and 6,028 works were made available in open access, including theses (315) and publications (5,713).
In a context in which open science is becoming increasingly important, these results confirm a fruitful and competitive scientific output, with a clear impact on the promotion of scientific culture and its dissemination.
One of the most striking figures of the past year is the number of collaborations with research centres worldwide: a total of 41,597, of which 311 were carried out in the United States, mainly at U.S. universities, making it a first-rate scientific partner.
With more than one hundred collaborations are Germany (118), Italy (119), the United Kingdom (109) and China (103), pointing to the University’s solid integration into Europe’s main research circuits, while also playing an increasingly significant role as a global scientific actor.
Beyond these main hubs, the distribution of collaborations with France (80), Brazil (79), India (54) and Canada (51), as well as with Asia-Pacific countries (Japan, Australia...) and Latin America (Chile, Colombia, Mexico...), illustrates an openness to the world that is not limited to a single geographical axis and highlights the University of Valencia’s capacity to adapt to different scientific and cultural contexts.
At the same time, the weight of collaborations with Spanish institutions - 413 in total -shows that international projection does not come at the expense of the national scientific fabric, but rather coexists with intense activity at the national level, with collaboration regarded as one of the structural pillars of research activity.
General data
The University of Valencia’s Scientific Production Portal currently registers 6,360 researchers (54.39% male and 45.61% female); 622 research groups; 1,064 projects; nearly 250,000 publications, around 111,500 of which are open access; and 15,472 theses - since 1999.
Regarding specialised indices in Science and Technology, the portal identifies Google Scholar as a benchmark, where the University’s three most cited researchers belong to the Department of Atomic, Molecular and Nuclear Physics. They are professor Santiago González de la Hoz , head of the Department, with 361,479 citations; senior lecturer María Moreno Llácer with 274,586 - both members of the Institute for Corpuscular Physics (IFIC) , a joint centre of the University of Valencia and the CSIC - and associate professor Miguel Villaplana Pérez , with 255,870.
Above 100,000 citations are Rafael Tabarés Seisdedos , professor of Psychiatry at the Faculty of Medicine and Dentistry (196,545), and professor María Dolores Corella Piquer , from the Department of Preventive Medicine, Public Health, Food Sciences, Toxicology and Legal Medicine at the Faculty of Pharmacy and Food Sciences (149,754).
Around 50,000 citations are recorded for professor of Inorganic Chemistry Eugenio Coronado , director of the Institute of Molecular Science (ICMol) ; emeritus professor José María Peiró Silla , professor of Social Psychology and founding director of the IDOCAL University Research Institute ; professor Francisco José Barba Orellana , from the Area of Nutrition and Food Science in the Department of Preventive Medicine, Public Health, Food Sciences, Toxicology and Legal Medicine; and professor Artemi Cerdà Bolinches , from the Department of Geography.
In Humanities and Social Sciences, the Dialnet Metrics index is led by the philosopher Adela Cortina , emeritus professor of Ethics and Political Philosophy at the University of Valencia , with 3,206 citations. Between 2,500 and 2,000 citations follow professor of Spanish Emilio Antonio Briz Gómez , emeritus professor José María Peiró Silla and emeritus professor Isabel Balaguer Solá - the latter two from Social Psychology. Between 1,999 and 1,500 citations are senior lecturer Melchor Gutiérrez San Martín , from the Department of Developmental and Educational Psychology , and professor Amparo Vilches Peña , from the Department of Experimental and Social Sciences Education.
Finally, researchers with between 1,499 and 1,000 citations are Isabel María Castillo Fernández , from the Department of Social Psychology ; José Fernando García Pérez , from the Department of Behavioural Sciences Methodology ; Jordi Solbes Matarredona , from the Department of Experimental and Social Sciences Education; and José Devís Devís , from the Department of Physical and Sports Education. All four are full professors.
Impact and visibility of the UV’s scientific output
According to the main international evaluation systems, the scientific output of the University of Valencia shows a high impact, reaffirming the visibility of its research activity. These are bibliometric indicators that measure the quality, impact and visibility of scientific publications. What is observed, according to the data collected in the portal, is a concentration in the most prestigious tiers, evidencing the reach and relevance of research results both for the scientific community and for society at large.
These citation-based indicators are: Journal Impact Factor (JIF) , SCImago Journal Rank (SJR) and Journal Citation Indicator (JCI). All three show a clear predominance in the highest-impact quartiles, Q1 and Q2, which group together the most influential journals in each field.
For the JCR (since 1997), the total results amount to 92,892, with more than 50% in Q1 (51,132), the quartile of maximum visibility and scientific impact; the remaining results show a decreasing distribution across Q2, Q3 and Q4.
The SJR (since 1999) reinforces this trend with an even larger volume in Q1 - 64,730 out of a total of 103,851- highlighting not only citation frequency but also the quality of the journals in which the work is published.
Finally, the JCI (since 2017) confirms the pattern with a significant concentration in the upper tiers: a total of 53,483, with 27,449 in Q1 and 13,250 in Q2.
Taken together, these results reveal a publication strategy oriented towards leading journals, with high international visibility and scientific recognition.
As for national indices, these are essential for assessing the editorial quality and the suitability to the Hispanic scientific context. This includes the Dialnet Journal Index , which comprises a total of 23,697 results distributed evenly across categories C1 to C4, with greater weight in the top levels - 8,892 in C1 and 5,656 in C2 - reflecting stability and editorial quality in leading journals.
On the other hand, the Integrated Classification of Scientific Journals (CIRC) , with a total of 26,424 results, shows a notable presence in the highest-quality categories, A+ (6,113) and A (2,847), along with a significant representation in levels B and C. This profile reflects thematic diversity and broad coverage of scientific dissemination channels.
The impact of research results as measured by these indicators also demonstrates the capacity of research to generate relevant knowledge, validated by the international scientific community and accessible to different audiences. Moreover, the combination of global and national indices provides a comprehensive view of the University’s scientific excellence, editorial rigour and commitment to knowledge dissemination.
On this latter point, an interesting figure from the portal is the language of publication, with the three most common being English (with 124,086 articles), Spanish (with 112,240) and Catalan (with 10,425).
In short, these results confirm a competitive and visible scientific output, aligned with the most demanding quality standards, contributing to the advancement of knowledge and its effective transfer to society - a transfer that is also measured by the 425 patents in which the UV is involved.
