Press Release (26 August 2010): Tel Aviv University astronomers reveal the nature of "separated pairs of asteroids"
		As a planetary scientist and astronomer, I use observations to study the physical nature of asteroids and their evolution. Recently, I completed my Ph.D. thesis at the Tel-Aviv University under the guidance of Prof. Dina Prialnik and Dr. Noah Brosch. I performed many observational campaigns at the Wise Observatory in Israel where I used time variable astronomy to derive lightcurves and rotation periods of asteroids. Knowing the rotation period, one can derive additional parameters such as shape, structure, density and the history of the asteroid such as the disintegration of asteroids into binary systems or separate objects. Currently, I am a post-doc in the experimental astrophysics group at the Weizmann Institute of Science under the supervision of Dr. Avishay Gal-Yam, where I derive photometric data from the Palomar Transient Factory (PTF) survey. In addition, I participate in many science outreach activities that include teaching and lecturing, street observations, and activities on the internet and in the media.
That's me and my C.V.
