Avishai Dekel

Dekel was awarded a Visiting Miller Professorship at UC Berkeley, a Blaise Pascal International Chair of Research by the École Normale Supérieure in Paris (2004–06), and a Lagrange fellowship in IAP Paris (2015–16).

He served as the Head of The Racah Institute of Physics (1997–2001), the Dean of the Authority for the Community and Youth at the Hebrew University (2005–2011), and the President of the Israel Physical Society (2008–11). He headed the university computing committee, was a member of the executive committee of the board of trustees and a member of the standing committee of the Hebrew University.

Dekel is known for his contributions to research in cosmology, especially the study of the formation of galaxies and large-scale structure in the Universe, which is dominated by dark energy and dark matter. His expertise is dwarf galaxies and supernova feedback (1986, 2003), large-scale cosmic flows and early estimates of fundamental cosmological parameters (1989-2001), the structure of dark-matter galactic halos (2000–2003), and the theory of galaxy formation (2003–2012).

Dekel earned his Ph.D. from the Hebrew University in 1980, and was a research fellow at Caltech and assistant professor at Yale University before joining the faculty of the Hebrew University in 1986.

Avishai Dekel (born 1951) is a professor of physics at the Hebrew University of Jerusalem, Israel, holding the Andre Aisenstadt Chair of Theoretical Physics. His primary research interests are in astrophysics and cosmology.
