Short bio

Maurizio Omologo obtained the Degree in Electrical Engineering at University of Padova (Italy) in 1984. From 1984 to 1987, he was researcher on speech coding at CSELT (Torino, Italy). In 1988, he joined ITC-irst (now FBK-irst), where he is the head of SHINE (Speech-acoustic scene analysis and interpretation) research unit (

Currently, main research areas of interest are: microphone arrays, speaker localization, speech analysis, source separation, speech enhancement, speaker identification, acoustic event detection, ASR for distant-speech interaction, audio signal processing for music information retrieval.

From 2001 to 2014, he taught "Audio Signal Processing and Coding" at University of Trento.

He acted, from 2006 to 2009, as Project Manager of the DICIT European Project and, from 2012 to 2014,  as Project Manager of the DIRHA European Project.

He is author of about 200 papers in major international conferences and journals in the field, and of 3 international patents.
