She did her PhD in the group of S. Haroche, where she fabricated Schrödinger cat states of light.
She was hired at CNRS in 2005 to realize quantum optics experiments with semiconducting quantum dots. She then took a theoretical turn.
She is expert in quantum thermodynamics, quantum information and quantum foundations, and works in close connection with experimentalists and theorists worldwide.
She heads Quantum Engineering Grenoble since 2017.

Research overview:
I am interested in the optical properties of semiconductor nano-structures and their application in quantum devices. This include in particular the optical study and control of the spin dynamics and the development of spin-photon interface for individual defects in semiconductors.
Biography:
I am Directeur de Recherche (Senior Researcher) at CNRS. I received a PhD degree from the University of Grenoble in October 2001. After a postdoctoral stay in the Quantum Optoelectronics group of the University of Southampton (Prof J.J. Baumberg group, now at University of Cambridge) where I developed optical coherent control experiments on individual quantum dots, I joined in Oct. 2003 the Laboratoire de Spectrométrie Physique (University of Grenoble and CNRS, now called LiPhy) as a Chargé de Recherche CNRS to start the optical study of the spin properties of magnetic and charged quantum dots. I joined in 2008 the Institut Néel. This gave me the opportunity to further develop my work on the optical properties of self-assembled II-VI quantum dots, with a more specific interest in optical control of spins and spin dynamics. I obtained in 2012 my Habilitation Degree in Physics from the University Grenoble Alpes and a position as Directeur de Recherche at CNRS in 2015.
An ongoing ANR funded project: MechaSpin.
