I am an Associate Professor at University of Western Brittany and part of the LaTIM, UMR 1101. My research work is focused on medical image reconstuction, with an emphasis on motion-compensated PET/CT. I am mostly interested in model-based iterative reconstruction and machine-learning techniques, and their implementation for the clinic. In this regard, I am at the interface between theoretical and translational research.

I obtained my PhD at the LTSI, UMR 1099, University of Rennes 1, jointly with Nanjing Southeast University. Following that, I did a postdoc at University College London, within the Institute of Nuclear Medicine.
