Nineteen ENAC professors named in new rankings


© ENAC/ has published its first rankings of top scientists in Earth Science, Engineering and Technology, and Environmental Sciences. Nineteen professors from EPFL’s School of Architecture, Civil and Environmental Engineering (ENAC) feature in the list. is one of the leading websites for engineering and technology research, offering data on scientific contributions since 2014. For the past eight years, the website has published rankings of the world’s top scientists in two fields: Computer Science, and Electronics and Electrical Engineering. In 2022, it introduced rankings for experts in 15 new disciplines.

The Engineering and Technology ranking, which features 10,875 scientists in total, includes nine ENAC professors. Seven of the names are civil engineers: Michel Bierlaire (887th in the world and 16th in Switzerland), Lyesse Laloui (924th and 17th), Ian F. C. Smith (1,124th and 21st), Aurelio Muttoni (4303th and 64th), Christophe Ancey (4488th and 67th) Edgard Gnansounou (4,744th and 72nd) and Eugen Brühwiler (5,825th and 78th). The remaining two are environmental engineers: Fernando Porté-Agel (1,247th and 26th) and Andrew Barry (1,694th and 31st).

In the Earth Science category, five ENAC scientists appear in a field of 6,741 names: David Andrew Barry (986th and 35th), Lyesse Laloui (1,184th and 39th), Anders Meibom (1,737th and 53rd), Michael Lehning (2,090th and 61st) and Anton Schleiss (5,072nd and 113th). Out of 9,198 researchers in the Environmental Sciences ranking, four are from ENAC: Athanasios Nenes (135th and 8th), Andrea Rinaldo (171st and 9th), Tom J. Battin (2,864th and 86th) and Alexis Berne (6,615th and 147th).

In Computer Sciences, Devis Tuia (2445th et 65th) and Alcherio Martinoli (4248th et 98th) are out of 9724 scientists. Professor Jean-François Molinari (607th and 8th) is out of 3,637 scientists in Mechanical and Aerospace Engineering.

The rankings are based on three criteria: the number of publications on Google Scholar and Microsoft Academic Graph; the h-index (the citation impact of a scholar’s publications); and the total number of citations over an entire career. This calculation method means that scientists who have been active in their discipline for longer are more likely to feature higher in the rankings.
