More specifically, I am interested in the study of nano-optical materials e.g. quantum wells, point defects in diamond or boron nitride, plasmonic and semiconductor nanostructures. The guiding thread of my research is based on understanding and exploiting the interaction of electrons (or light) with matter using light (or electrons). To do so, I have studied the optical properties of materials with cathodoluminescence (CL), using different types of scanning electron microscopes, with various characteristics ranging from nanometer spatial resolution to picosecond temporal resolution. My main contribution to this research field is the discovery of photon bunching by CL: under irradiation of an electron beam, semiconductors emit light by packets of photons. This phenomenon provides a unique tool for understanding electron-matter interactions, measuring the lifetimes associated with excited states at the nanoscale, and measuring the efficiency of electron excitation. As an independent researcher at CEMES, I am developing new time-resolved electron-based spectroscopy techniques for nano-optics using the unique electron microscope already available and in operation on site. These techniques and their applications to nano-optics are entirely new. **EDUCATION** 2012-2015 PhD in Physics, University Paris Saclay (France) Thesis: Intensity interferometry experiment in a scanning transmission electron microscope *Laboratory of Solid state physics* , University: *Paris Saclay* (*Orsay, France)* Advisor: Mathieu Kociak and Luiz Tizei **Keywords:** STEM, single-photon emitter, g(2) in CL, GaN-based heterostructure 2011-2012 Master in nanoscience and nanotechnology Engineering School: *Phelma (Grenoble, France)* 2011-2012 Master in Condensed Matter Physics University: *Joseph Fourier (Grenoble, France)* **CURRENT POSITION** Dec 2018 – CNRS Permanent Researcher (Chargé de Recherche) Laboratory: *CEMES-CNRS (Toulouse France)* **POSTDOCTORAL POSITION** 2016 – 2018 Post-doctorate – Albert Polman’s group Laboratory: *AMOLF (Amsterdam, The Netherlands)* **Keywords:** Time-resolved SEM, photoemission, ultra-fast blanker, TR-CL, g(2) in SEM **ORGANISATION OF SCIENTIFIC MEETINGS** 2019-2022 Co-chair of QEM School (2022) in Quantitative Electron Microscopy 2019-2021 Member of Nano-Optics and Plasmonics Subcommittee of the OSA Conference on Lasers and Electro-Optics (CLEO) 2021-2022 Sub-Committee Chair of the conference on Lasers and Electro-Optics (CLEO)
