I am a CNRS researcher, working at the Sisyph laboratory, École Normale Supérieure de Lyon (Lyon, France). My research lies at the intersection of signal processing and machine learning. I am particularly interested in the theory of inverse problems and applications in computational imaging.

Before joining the CNRS, I did a postdoc in Mike Davies group at the University of Edinburgh (Edinburgh, UK) and a PhD at Heriot-Watt University (Edinburgh, UK) and TéSA lab (Toulouse, France) under the supervision of Yoann Altmann, Jean-Yves Tourneret and Steve McLaughlin.
