He earned a PhD in Biospectroscopy from the Pharmacy University of Reims Champagne-Ardenne under the guidance of Prof. Manfait and Sockalingum. He has a 20 year long experience in the field of vibrational microspectroscopy of biological materials, cells and tissues including two post-doctoral fellowships in Canada, at the Chemistry Department of Université de Montréal working with Prof. Lafleur, and at the Chemistry Department of St Francis Xavier University with Prof. Pink and Smith-Palmer. His first research interests focused on the early identification of pathogenic microorganisms by infrared spectroscopy, the study of biocide penetration in bacterial biofilms with ATR-FTIR, and pioneering the analysis of bacterial biofilms by Raman microspectroscopy. He joined the French national synchrotron light source, SOLEIL, in 2008 and has since been helping scientists perform experiment in various fields of science such as cultural heritage, plant biology, cell chemistry, catalysis, astrophysics... He has used the bright IR synchrotron light to conduct various studies in biochemistry: to profile induced pluripotent and embryonic stem cells, to monitor tyrosine kinase activity in multiresistant hematopietic progenitor cells, to study the chemical changes associated with tumor hypoxia, to follow the penetration of IR probes in living cells and tissues, to study abnormal protein conformation in diverse neurodegenerative diseases.
