I am a research scientist at the French National Centre for Scientific Research CNRS, 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 imaging 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.
