Dr. Florine Cavelier is CNRS Research Director at the Institute of Biomolecules Max Mousseron (IBMM) in Montpellier (France). She obtained her Ph.D. in Organic Chemistry at the University of Montpellier in 1989 working on lanthionines, thioether-bridged peptides with antibiotic properties. She spent two years as a Royal Society Fellow at the Dyson Perrins Laboratory (with Prof. Jack Baldwin, Oxford), where she studied the biosynthesis of iso-penicillin. Next, she obtained an academic position at the National Center for Scientific Research (CNRS) and was promoted to Research Director in 2003. She currently heads the “Stereoselective synthesis and unnatural amino acids” team at IBMM. She was a board member (2007-2022) and president (2011-2013) of the “French Group of Peptides and Proteins”. She was elected French representative of the European Peptide Society Council (2012-2020) and was appointed to the EPS Executive Committee as Scientific Affairs Officer (since 2020). Her research interests focus on unnatural amino acids (incl. silicon-containing amino acids) able to modulate the properties of biologically active peptides and increase their proteolytic stability.
