Éric Bavu

Senior Lecturer (HDR)


Cnam Paris

I am a lecturer at Cnam Paris since September 2009, in the acoustics team of the Laboratoire de Mécanique des Structures et des Systèmes Couplés .

To date, I have officially co-supervised PhD students (4 defended, 2 in progress since December 2021), and I am leading since early 2019 the ANR Deeplomatics until June 2022.

I defended my accreditation to supervise research (HDR) in December 2019. My habilitation thesis has been deposited on HAL , and I leave available a chaptered video of the defense as well as the slides in html.

My research activities are focused on inverse problems in acoustics, signal processing associated with microphonic arrays, and Deep Learning methods for acoustics.
