His research work deals with the effects of interactions in low-dimensional quantum systems, such as Luttinger liquids, and on the effects of disorder in classical and quantum systems, with works showing the existence of novel disordered phases such as the Bose glass and the Bragg glass. In 2000, he received the Abragam Prize from the French Academy of Sciences.

He is the author of about 220 publications, 10 chapters of books, and one monograph "Quantum physics in one dimension" with Oxford.

He is a referee for many journals and funding organizations, has been an editor and a "Distinguished Referee" of Europhysics letters and has been recognized as an "Outstanding Referee" by the APS.

He has also served on the boards of several scientific institutions, such as the CNRS theory committee and the "Les Houches School of Physics" administrative board.
