Bertrand BercheIJL, University de LorraineBertrand Berche was born on May 6, 1963 in Metz, France. He obtained his MSc in physics and applied physics in 1987 from Henri Poincar\'e University of Nancy, later completing his PhD studies here in 1991. Since then, B. Berche has remained at the same university, which in 2009 became a part of the University of Lorraine, as Ma\^itre de Conf\'erences. He habilitated in 1997 becoming a full professor in 1998. Between 20082011 B. Berche was President of the Condensed Matter Section of the National Council of Universities, France. In 20082013 he was Director of the Physics Department at the University of Lorraine, and since 2007, has been involved in the organization of the FrenchGerman Doctoral College which subsequently became the ${\mathbb L}^4$collaboration between Leipzig, Lorraine, Lviv and Coventry. He was advisor and coadvisor of ten PhD students and has been awarded the degree of Doctor Honoris Causa of the Institute of Condensed Matter Physics of Lviv in 2016. His research concerns mainly statistical physics, theoretical condensed matter physics and history of sciences.Personal webpage 

Christophe ChatelainIJL, University de LorraineChristophe Chatelain was born on 23 July, 1974 in Epinal (France). He received a MSc in physics from the university of Nancy, now part of the university of Lorraine. Under the supervision of Bertrand Berche, he studied by Monte Carlo simulation the influence of disorder on the phase transition in lattice spin models, in particular the Potts model. He defended his PhD in June 2000, before leaving to Leipzig to work with Wolfhard Janke. Hired by the university of Lorraine in 2001, Christophe Chatelain developed research activities in statistical physics in various directions, particularly in the study of aging phenomena in quenched systems and of random classical spin models as well as quantum spin chains. During the academic year 20122013, he was a visiting professor at the Indian Institute for Science, Education and Research (IISER) at Thiruvananthapuram (India). He defended his habilitation to supervise research in December 2012. He also enjoys giving science conferences to abroad audience.Personal webpage
