Dr. Massimiliano Todisco is an Assistant Professor within the Digital Security Department at EURECOM, France. He received his Ph.D. degree in Sensorial and Learning Systems Engineering from the University of Rome Tor Vergata in 2012. Currently, he is serving as principal investigator and coordinator for TReSPAsS-ETN, a H2020 Marie Skłodowska-Curie Innovative Training Network (ITN) and RESPECT, a PRCI project funded by the French ANR and the German DFG. He co-organizes the ASVspoof challenge series, which is community-led challenges which promote the development of countermeasures to protect automatic speaker verification (ASV) from the threat of spoofing. He is the inventor of constant Q cepstral coefficients (CQCC), the most commonly used anti-spoofing features for speaker verification and first author of the highest-cited technical contribution in the field in the last three years. He has more than 90 publications. His current interests are in developing end-to-end architectures for speech processing and speaker recognition, fake audio detection and anti-spoofing, and the development of privacy preservation algorithms for speech signals based on encryption solutions that support computation upon signals, templates and models in the encrypted domain.
