“Receiving the appointment as an ACM Fellow is an immense honor for me, especially considering that many of the researchers who inspired my career hold this title". These are the words of Paolo Ferragina, Full Professor of Computer Science at the Scuola Superiore Sant'Anna in Pisa, who has been appointed as a new member of the Association for Computing Machinery (ACM), the world's foremost organization in the field of computer science. The ACM was founded in 1947 and is based in New York. It brings together researchers, educators, and practitioners to improve computing science, engineering, and applications. Each year, the ACM bestows the prestigious Turing Award, which is comparable to the Nobel Prize in Computer Science. Fewer than one percent of its members worldwide are granted the Fellow title. This honor is intended for scholars whose work exemplifies great scientific brilliance and has had a long-term, global impact on their discipline. Ferragina is one of 71 new members chosen from the association's membership for their revolutionary contributions in computer science, and the only one from an Italian university. In particular, Ferragina was selected as a new member of the ACM in recognition of his contributions to data structures and algorithms that facilitate efficient search and data compression. With a PhD in Computer Science from the University of Pisa and a postdoctoral fellowship at the Max Planck Institute for Informatics, Ferragina has been a full professor since 2007, first at the University of Pisa and, since 2025, at the Sant’Anna School.
