From 2012 to 2015, Quentin was a Ph.D. student at the CNRS Institut de Chimie des Substances Naturelles (ICSN) Mass Spectrometry team in Gif-sur-Yvette, France. His thesis was titled “Mass Spectrometry Imaging of Natural Substances,” and his work included surface analysis of organic compounds on a variety of samples (biological and inorganic). Quentin developed expertise in Time of Flight Secondary Ion Mass Spectrometry (TOF-SIMS) and Matrix Assisted Laser Desorption/Ionization coupled to Time of Flight (MALDI-TOF). One of the major contribution of his thesis consisted to optimize and to characterize a new operating mode for TOF-SIMS by introducing delayed extraction of secondary ions.
In 2017, Quentin worked as a Post-doctoral Associate at Florida International University in Miami, USA. He analyzed kinetic uptake and biodistribution of drugs by single cells via TOF-SIMS.
From 2017 to 2022 Quentin has worked as a Team Leader in Biotransformation and Biodistribution at Technologie Servier Drug Metabolism and Pharmacokinetic (DMPK) Department in Orléans, France. In this role, Quentin led metabolism and biodistribution studies for small molecules and therapeutic oligonucleotides.
Quentin has also worked in 2023 as a Research Engineer at CNRS Laboratoire d’Archéologie Moléculaire et Structurale (LAMS) in Paris, France. He conducted surface analysis on samples from cultural heritage and patrimony and data processing for TOF-SIMS analysis.
