Aurelien PerronAurelien Perron earned his doctorate in Physical Chemistry in 2008 from the University of Burgundy in Dijon, France, and worked for the National Center for Scientific Research (CNRS) and the French Alternative Energies and Atomic Energy Commission (CEA) until 2013. Then, he started work at Lawrence Livermore National Laboratory (LLNL) as a postdoc under the international agreement between DOE/NNSA and CEA/DAM (France) on cooperation in fundamental science supporting stockpile stewardship collaborative work.

His research focuses on phase stability, phase transformation, microstructure evolution, and alloy design of various classes of materials. He uses the CALPHAD (CALculation of PHAse Diagrams) method to establish self-consistent thermodynamic databases for multicomponent systems. These databases, assessed using experimental information and ab initio data where needed, can then be used to calculate phase stability of complex multicomponent systems as functions of temperature and composition, predict microstructure evolution (input for phase-field modeling), or design new alloys (optimization).
 
As leader of the “Advanced Search for High-performance Materials (AS4HPM)” project, Perron focuses on developing a CALPHAD thermodynamic database for the {Al, Ce, Cu, Fe, La, Mg, Ni, Si, Zn, Zr} system and its integration into our Materials Design Simulator (MDS project, FA 2.1.6 from previous CMI cycle) to design new alloys in collaboration with CMI partners.
