During her PhD (obtained in 2002, about the synthesis, theoretical and spectroscopic studies of fluorescent ligands with pi-extended conjugation) and her post-doctoral internship (under the supervision of Prof. J. Michl, University of Colorado, Boulder, USA), S. Leroy-Lhez developed her taste to work on multidisciplinary projects, especially in organic synthesis, photophysics and photochemistry. Since then, she is working on both aspects, being convinced of the wealth of results resulting from their synergy. With this versatility, she was recruited as associate professor in 2003 at the laboratory Moltech Anjou (University of Angers) and moved in 2011, to University of Limoges (PEIRENE laboratory). Since 2018, she is the coordinator of the H2020 – EJD n°764837 POLYTHEA project “How light can save lives”. Her research activity focuses on the design of molecular systems and the study of their structure-property relationships for phytosanitary applications in photodynamic treatments. She is the author of 36 research papers in peer-reviewed journals and 1 book chapter.
