The International Conference on Computational Intelligence Methods for Bioinformatics and Biostatistics (CIBB) was founded by Roberto Tagliaferri (Università di Salerno, Italy), Francesco Masulli (Università di Genova, Italy), and Antonina Starita (Università di Pisa, Italy) in 2004. The conference started as a special session of the 14th Italian Workshop on Neural Networks (WIRN 2004) in Perugia (Italy), and was a special session of international conferences organised in Italy for its first four editions. CIBB became an independent conference in October 2008 with its first edition in Vietri sul Mare (Italy), held a few months after the sad demise of CIBB founder Antonina Starita (1939-2008). Since 2004, the CIBB conference series generated 12 proceedings books, 4 sections of proceedings books, and 9 journal supplements, that contain around 400 peer-reviewed original scientific publications altogether. CIBB 2023 is back as an in-person conference after the 2021 virtual edition.
