I am currently a postdoctoral researcher at LS2N in Nantes, focusing on the problem of bandwidth extension, and more generally on audio synthesis, using deep learning models.

I did my PhD research on the problem of speaker localization and counting with deep neural networks.

My other research interests include music information retrieval, music generation and sound synthesis.
