Avishai Dekel

Avishai Dekel is a Professor of physics at the Hebrew University of Jerusalem, Israel, doing research in astrophysics and cosmology. Professor Dekel got his Ph.D. degree from the Hebrew University in 1980, and was a research fellow at Caltech and an Assistant Professor at Yale University before joining the faculty of the Hebrew University in 1986. Served as the Head of the Racah Institute of Physics, 1997–2001, and is the Dean of the Authority for the Community and Youth at the Hebrew University since 2005, Professor Dekel is a frequent visitor to the University of California, Santa Cruz. He has been awarded a Miller professorship at UC Berkeley and a Blaise Pascal International Chair by Ecole Normale Superiere in Paris, 2004–2006. Professor Dekel is known for his contributions to research in cosmology, especially the study of the formation of galaxies and large-scale structure in the dark matter-dark energy-dominated Universe. He is most well known for his contribution to the understanding of dwarf galaxies via supernova feedback (articles with Silk in 1986 and Woo in 2003), for the analysis of cosmic flows (articles with Bertschinger and Faber 1989–1997), and his contributions to other major issues in the theory of galaxy formation (e.g., his articles with Birnboim in 2003–2007).
