Our research teams

This Institute is organized into five research teams covering coherent areas of activity but which are based on different and highly complementary segments, giving rise to original transversal projects.

On the basis of fundamental and specific expertise, CEISAM is positioned in a certain number of niches of excellence at the interface with the fields of Health, Food chemistry and Materials, through privileged interactions at regional, national and international levels.

Platforms and equipment

To support our research activities, the CEISAM Institute owns many specialist equipments.

These instruments and equipment chains, sometimes intégrated into platforms, aim to synthesize, model, prepare and characterize organic or hybrid items. The European Union, the CNRS and the "Pays de la Loire" region have largely contributed to co-financing these platforms and equipments in particular in NMR, Mass Spectrometry, Molecular Modeling, Optical spectroscopies and microscopy.
