Dr. Margaux Fresnais obtained her PhD of chemistry at the University of Strasbourg (France) in 2016. Since then, she dedicated her activities to the development of mass spectrometric (MS) methods for targeting therapeutic antibodies and small-compound pharmaceuticals for personalized medicine. She has a large expertise in MS methods ranging from MALDI- to ESI-MS for the targeted quantification of drugs, drug metabolites and surrogate markers, but also in “omics” methods for the discovery of new markers of pathologies and treatment efficacy.
