Frédéric Bimbot received the B.A. degree in linguistics from Sorbonne Nouvelle University, Paris, France, in 1987, the telecommunication engineer degree from ENST, Paris, in 1985, and the Ph.D. degree in signal processing in 1988. In 1990, he joined the French National Center for Scientific Research (CNRS) as a Permanent Researcher. He was with ENST for seven years and then moved to IRISA (CNRS and INRIA), Rennes, France. He also repeatedly visited AT&T Bell Laboratories between 1990 and 1999. He has been involved in several European projects: SPRINT (speech recognition using neural networks), SAM-A (assessment methodology), and DiVAN (audio indexing). He has also been the work-package Manager of research activities on speaker verification, in the projects CAVE, PICASSO, and BANCA. His research is focused on audio signal analysis, speech modeling, speaker characterization and verification, speech system assessment methodology, and audio source separation. He is heading the METISS Research Group at IRISA, dedicated to selected topics in speech and audio processing. Dr. Bimbot was Chairman of the Groupe Francophone de la Communication Parlée (now AFCP) from 1996 to 2000 and from 1998 to 2003, a member of the International Speech Communication Association Board (ISCA), formerly known as ESCA.
