Ludwik Leibler, born in 1952 is a Polish-born French physicist. He is Professor of École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI ParisTech) and member of the French Academy of Sciences and National Academy of Engineering. Ludwik Leibler received his PhD in 1976 in Theoretical Physics from Warsaw University, and then spent two years as a post-doctoral fellow at the Collège de France in Paris under the direction of Pierre-Gilles de Gennes. He is a researcher in Centre National de Recherche Scientifique (CNRS) which he joined first in Stasbourg then in Paris where he worked on theoretical and experimental aspects of polymer self-assembly and dynamics, interfaces, gels and charged polymers. From 1996 to 2003 he was the founding director of a joint laboratory between CNRS and chemical company Elf Atochem (later Arkema) which regrouped researchers from academia and industry. In 2001 he became professor of Soft Matter and Chemistry at École Supérieure de Physique et Chimie Industrielles in Paris where his research interests include influence of molecular disorder on mesoscopic structure and properties of polymer materials, impact resistance, fracture and adhesion, design of stimuli responsive materials and supramolecular chemistry.
