Director of research at the CNRS and head of the mass spectrometry team at the Institute of Chemistry of Natural Substances (ICSN), David Touboul was recruited as a lecturer in environmental analytical chemistry at the École Polytechnique. Part of his activity will be dedicated to the development of new methods by combining chromatography (LC and SFC) and imaging approaches with mass spectrometry, including the FT-ICR mass spectrometer from Infranalytics.
