Biography

I am a CNRS researcher in the SVH team of Laboratoire Jean Kuntzmann (LJK) at University Grenoble Alpes (UGA). My research interests include image and signal processing, wavelets, convolutional neural networks, stochastic processes and graphs analysis.

I was previously a postdoctoral fellow in a LIG team for the Data Institute of UGA where I worked with Éric Gaussier, Adeline Leclercq-Samson, Julien Chevallier and Jean-Marc Francony. I have defended my PhD thesis in December 2017, under the supervision of Valérie Perrier, Marianne Clausel and Laurent Condat. Before that, I was graduated from the École nationale supérieure d’informatique et de mathématiques appliquées, an engineering school of the Grenoble INP Institute of Technology.
