I'm an astronomer at Ben Gurion University, Israel. I study mainly the evolution and formation of the first and farthest galaxies, as well as the distribution and properties of dark matter, exploiting a beautiful phenomenon called gravitational lensing. Perhaps my main expertise is the analysis and modeling of strong gravitational lenses, a few impressive examples of which are seen throughout this site.
Before becoming faculty in BGU, I was a NASA Hubble Fellow at Caltech, and before that I was a postdoc at the University of Heidelberg, after finishing my studies in Tel-Aviv University.
