This classification, compiled from Scopus data provided by Elsevier, identifies the top 2% of scientists globally based on their citation count in 2025. The presence of these researchers on the list signifies recognition of the quality, continuity, and impact of the center's scientific activity.
The distinguished scientists cover diverse fields of knowledge, including solar technologies, energy, physics, materials, environmental research, and biomedicine, reflecting the breadth of research lines developed at CIEMAT. They include both active and recently retired specialists.
The Stanford ranking generates two classifications: one analyzing the researcher's career-long impact up to 2025 (list A) and another focused on the last year, 2025 (list B). The A+B classification indicates that the researcher appears on both lists.
Among the CIEMAT researchers included in the ranking are Manuel Aguilar, Concepción Aravaca, Antonio L. Ávila-Marín, Mercedes Ballesteros, Julián Blanco, M. J. Benito, Antonio M. Chaparro, Paloma Ferreira-Aparicio, Cecilia Guillén, Eric R. Hodgson, Sixto Malato, Lorenzo Malerba, Paloma Manzanares, Alberto Martilli, Nuria Martín Chivelet, Isabel Oller, Jesús Polo, Vadim N.
