Francesco Tosoni (IPA: [fraŋ'ʧesko to'zoːni]) pursued a PhD in Computer Science Click here to download a PDF document. at the University of Pisa, under the supervision of Professors P. Ferragina and G. Manzini. His PhD dissertation was titled Computation-friendly Compression of Matrices and Tries. He has been a member of the Acube laboratory (A³, Advanced Algorithms and Applications) directed by Professor P. Ferragina.

His research interests include lossless-compression algorithms and data structures, string indexing and stringology in general, and Big Data analytics.

He received his BSc degree in Computer and Electronic Engineering Click here to download a PDF document. from the University of Perugia. He then continued his studies at the University of Pisa, earning in 2020 a MSc degree in Computer Science and Networking Click here to download a PDF document., a joint programme with the Sant’Anna School of Advanced Studies. His MSc thesis titled Algorithms and Data Structures for Efficient Ride Sharing Platforms won the Con.Scienze 2020 Best Thesis Award.

In 2020, he received a scholarship and study grant on the topic "Algorithms and data structures for urban mobility platforms" at the University of Pisa. That same year, he obtained the qualification to enrol in the register of engineers (section A, information engineering sector).

From 8th September to 20th December 2022 he was a visiting student at Professor Gonzalo Navarro's laboratory at the University of Chile in Santiago.
