Since Nov. 2014 CNRS researcher in the team “Chimie du Solide et Matériaux” of the Institut des Sciences Chimiques de Rennes (ISCR), Université de Rennes 1, France.

2020 Habilitation (HDR) from University of Rennes 1.

2012-2014 Post-doctoral researcher at the CRISMAT laboratory, ENSICAEN, Caen, France, under the supervision of Dr. Y. Bréard, Dr. E. Guilmeau and Pr. S. Marinel.

  • Study of the influence of non-conventional sintering methods (microwave and spark plasma sintering) on the microstructure and magnetic properties of Nd-Fe-B permanent magnets, in collaboration with Dr. S. Rivoirard, Dr. N.M. Dempsey and Dr. D. Givord, Institut Néel, Grenoble, France.

  • Study of the influence of temperature on the crystal structure, purity and thermoelectric properties of sulphides materials.

2011-2012 Post-doctoral researcher in the Department of Physics and Astronomy at the University of Manitoba, Winnipeg, MB Canada, under the supervision of Pr. J.M. Cadogan.

  • Study of the magnetic structures of ternary intermetallic compounds with a high thermal neutron absorption cross-section rare-earth element (Sm, Eu, Gd) by neutron powder diffraction and Mössbauer spectroscopy (119Sn, 151Eu, 153Eu, 155Gd), in collaboration with Pr. D. Ryan, McGill University, Montreal, QC Canada.

2008-2011 Ph.D. student in the research team “Composés Métalliques et Matériaux Hybrides” of the Institut Jean Lamour, Université Henri Poincaré Nancy I, France, under the direction of Pr. B. Malaman and Dr. A. Vernière: Contribution to the structural and magnetic properties of intermetallic compounds crystallizing in the CeScSi- and Th6Mn23-type structures.

Research themes

Synthesis and study of the chemical, structural and magnetic properties of inorganic materials for energy conversion combining X-rays diffraction, neutron diffraction and Mössbauer spectroscopy:

  • Study of the crystal structure, reactivity and thermal stability of complex thermoelectric copper-based sulphide materials: colusites Cu26T2M6S32 (T = V, Cr, Mo, W; M = Ge, Sn), germanite Cu22Fe8Ge4S32, tetrahedrite Cu12Sb4S13, Cu4Sn7S16 ...

  • Crystal structure resolution and refinement of new octahedral metal atom cluster compounds.

  • Crystal and magnetic structure resolution of uranium-based intermetallic compounds.

  • Study of the magnetic and magnetocaloric properties of sulphide and intermetallic materials.

Technical skills

• Sample elaboration: high frequency induction, arc-melting and conventional furnaces, Mo crucible and microwave heating synthesis.

• Crystallographic structure determination: powder and single-crystal X-rays diffraction, powder neutron diffraction.

• Magnetic and magnetocaloric characterization: DC, AC and magnetic entropy change measurements.

• Magnetic structure determination: neutron powder diffraction and Mössbauer spectroscopy.
