Paillard Charles

Charles Paillard is a Research Professor in the Department of Physics at the University of Arkansas since 2023. Prior to that, he was a tenured Associate Professor from 2018 to 2023 in the Structure, Properties and Modelling of Solids lab in CentraleSupélec, one of France's top engineering college, and University Paris-Saclay. There, he made significant contributions to the field of ferroelectrics and multiferroics, and in particular their interaction with light. During his post-doctoral position at the University of Arkansas from 2016 to 2018, C. Paillard developed an original constrained-Density Functional Theory occupation number method to mimic the effect of thermalized photo-excited carriers on the structure of semiconductors and insulators. He also made significant contributions in the modelling of electro-optic effects using ab-initio methods. During his PhD in Physics, which he obtained in 2016 from University Paris-Saclay, one of Europe's top university, Charles Paillard pioneered the exploration of ab-initio methods for the study of photostriction, the deformation induced in solids when visible light is absorbed. He also made contributions to the field of phase transitions in relaxor-ferroelectric systems, forr which he was awarded a best poster award at the international European-Materials Research Society Fall meeting in Warsaw, Poland, in 2015. C. Paillard has published more than 40 articles in peer-reviewed journals, and been invited to give talks and lectures in 10 international conferences or schools. He continues to actively contribute to the field of ferroelectrics and multiferroics, pursuing a better understanding of their interaction with visible light both experimentally and theoretically.
