He studied Physics in Tel Aviv University, completing his Ph.D in 1998. He then joined Bob Silbey in M.I.T for his post-doc studies. In 2002 he joined the faculty of Notre Dame University and in 2004 returned to Israel.
His main research is in the field of non-equilibrium statistical mechanics. In particular he helped develop the theory of fractional kinetic equations for anomalous diffusion and relaxation, theory of single molecule spectroscopy, and weak ergodicity breaking. Among the physical systems he studied are blinking of quantum dots, the diffusion of cold atoms in atomic traps and the diffusion of single molecules within a live cell. He receives several prizes: the Krill prize (2006, selected by the Wolf foundation), the Michael Bruno Memorial award (2009, selected by Yad Hanadiv) and the Friedrich Wilhelm Bessel Research award (2011, selected by the Alexander von Humboldt foundation).
