After completing postdoctoral research at the Royal Institution in London, she joined the University of Bordeaux in 1994 and was promoted to Professor in 2010.She has long conducted research at institutions affiliated with the French National Centre for Scientific Research (CNRS), including the IInstitut de Chimie de la Matière Condensée de Bordeaux (ICMCB, 2010–2022) and the Centre de Recherche Paul Pascal (CRPP, since 2022).In 2010, she was awarded the Chevalière dans l’Ordre des Palmes Académiques. In 2015, she received the Chevalière dans l’Ordre National du Mérite. She was elected as a member of the Institut Universitaire de France (IUF) during 2010–2015 and 2024–2029. From 2020 to 2022, she was consecutively listed in World's Top 2% Scientists ( 2022 : 652th on 57422 in Inorganic and Nuclear Chemistry). In 2024, she won the Award French Chemical Society (SCF) – Coordination Chemistry Division. In academic service, she is the member of the Editorial Advisory Board of Inorganic Chemistry and has organized multiple academic events, including Gordon Research Conferences and the International Conference of Molecular Magnetism ICMM’25. As a core member of the Molecular Materials and Magnetism (M₃) team, her research focuses on the photomagnetic effects of photoinduced electron transfer molecular compounds High-Tc molecular-based magnets. She has led several multinational research projects.To date, she has published 152 research papers and 7 book chapters, with an h-index of 49 and over 8,600 total citations.

报告简介：The rational design of molecular systems, which exhibit light-switchable physical properties is still a subject of the intense research activity. Over the past, chemists have investigated magnetic and photoresponsive complexes through rational choices of cyanido based building blocks . This approach has been extremely successful, and various molecular architectures have been obtained with remarkable properties such as spin crossover, electron-transfer process, and photoinduced magnetism. The understanding of the electronic mechanism during the photo-excitation is not an easy task using only magnetic properties. The use of structural X-ray probes is necessary to better understand the photomagnetic mechanism .

In this presentation, the design and the switching properties of three cyanido-bridged dinuclear compounds, namely [(Tp)Fe^III(CN)₃Co^II(Py5Me₂)](X) (Py5Me₂ = 2,6-bis(1,1-bis(2-pyridyl)ethyl)pyridine, Tp = hydridotris (pyrazol-1-yl)borate, X = OTf, PF₆ and AsF₆) will be analyzed using a combination of crystallography, magnetic properties, and X-ray Absorption Spectroscopy (XAS) measurements. The bulk and local structural measurements have shown the thermal- and photo-induced electron transfer.
