I am an astrophysicist in the Department of Natural and Life Sciences at the Open University of Israel.
My field of research is cosmology - the science that studies the Universe as a physical entity and explores its overall properties, formation and evolution. In particular, I work on various issues related to the formation and evolution of the Large Scale Structure of the Universe as probed by a number of astrophysical tracers (i.e., galaxy peculiar velocities, redshift galaxy surveys, Cosmic Microwave Background anisotropy, the Lyman-α forest observed in the spectra of distant quasars and the 21 cm hyperfine spin-flip transition of neutral hydrogen).
Currently, my main scientific activity is centered on studying the Epoch of Reionisation (EoR) of the Universe -- the period during which the gas in the Universe transformed from neutral to ionised. More specifically, I am a member of the LOFAR-EoR key Science project of the LOFAR radio telescope, which is the most promising instrument for studying this epoch.
