After Claire Colin obtained her PhD at the Laboratoire de Physique des Solides, Orsay, in 2005; she was a post-doctoral fellow at the Zernike Institute for Advanced Materials, Groningen University in The Netherland. She became Associate Professor in 2007 joining the Néel Institute. Since 2012, she is also scientific co-responsible for the neutron powder diffractometer D1B (CRG at Institut Laue Langevin, ILL). The research activity of Claire Colin is focused on the structure-property relationship of several multiferroic and magnetoelectric systems. Her expertise lies in physical characterization (electric and magnetic properties) but also in fine structural characterizations mainly by neutron and X-rays powder diffraction. She is specialized in the of symmetry mode analysis that is very useful for establishing the driving mechanisms for stabilizing crystallographic and magnetic structures.
