Ram (Ramy) Brustein (Hebrew: רם ברושטיין; born: 1957) is a Professor in the Department of Physics at Ben-Gurion University (BGU), Israel, where he holds the Albert Einstein Chair in Theoretical Physics.[1][2]
His research focuses on theoretical physics and cosmology.
Early life and education
[edit]Ramy Brustein was born in kibbutz Metzer, Israel. He began his academic studies in Physics and Mathematics at Tel Aviv University in 1978, and received his B.Sc. (with honors) in 1982, and M.Sc. (with honors) in 1984.[3]
He continued his Ph.D. studies at Tel Aviv University until 1988. His thesis on “String Propagation in Background Fields and Conformal Field Theories in Two Dimensions” was supervised by Prof. Shimon Yankielowicz.[1]
Career
[edit]In 1988 Brustein was a postdoctoral research fellow at the University of Texas at Austin In the Weinberg theory group, and later at the University of Pennsylvania. Brustein became the first Israeli fellow at CERN in 1993, and two years later he joined Ben-Gurion University as a Senior Lecturer. He became an associate professor in 2000, and was promoted to full professor of Physics in 2004.[4]
In 2016 he became the incumbent of the Albert Einstein Chair in Theoretical Physics.[2]
Brustein has supervised 24 graduate students and post-doctoral researchers at BGU, several of them hold faculty positions in Institutions in Israel and abroad and authored over 160 scientific publications.
During the years Brustein held visiting academic positions at other universities and research institutes, including: CERN, TH Division, Geneva; KITP, University of California, Santa Barbara; University of Paris 7; Center for Advanced Studies, Ludwig Maximilians University, Munich; Flatiron Institute, New York; Institute for Advanced Study, Princeton; NYU, New York.[5][6]
Brustein held several official positions at Ben Gurion University, including Dean of the Kreitman School of Advanced Graduate Studies (2006-2010), Senate Member (2006-2010, 2013-2018) and Chair of the Department of Physics (2015-2018).[7]
Brustein also held professional consulting positions. He was an advisor for the US-Israel Binational Science Foundation (2000-2003), a consultant at the School of Physics and Astronomy, Tel Aviv University (2008-2009) and since 2006 he is an advisor for the Israel Science Foundation.
Research
[edit]Brustein’s work focuses on the Interface of early universe cosmology and astroparticle physics with fundamental physics. He is also interested in quantum gravity, quantum black holes and quantum cosmology.[8]
Brustein’s research on the interface between theoretical particle physics and cosmology, combining research in Einstein's theory of gravity and its generalizations, string theory, and quantum black holes, in particular the nature of singularities in gravity. Several articles in the field that are highly cited contributions: inflation in string theory, gravitational waves from before the Big Bang, identification of dark energy properties, thermodynamics of black holes and the universe.
In 1992, together with Prof. Paul Steinhardt, Brustein showed that cosmological inflation is unlikely within simple string theoretic models, suggesting the need for an alternative origin of the Universe.[9] In 1995, together with Profs. Maurizio Gasperini and Gabriele Veneziano, Brustein predicted that such an alternative origin of the Universe, which includes a pre-big-bang phase should produce a strong gravitational wave signal, which could be detetected by current gravitational wave observations.[10]
In 2000, together with Prof. Gabriele Veneziano, he proposed a fundamental bound on the information capacity (entropy) of the Universe which suggests that the big-bang should be replaced by a quantum phase, supporting the existence of a pre-big-bang phase in the history of the Universe.[11]
In 2019 Brustein introduced, together with Prof. Joey Medved, a model which later was named the “frozen star model”. The model, which describes a type of black hole mimicker ultracompact astrophysical objects that are free of singularities, lack a horizon, but yet can mimic all of the observable properties of black holes. By eliminating horizons and singularities, the model offers a solution to some of the paradoxes in black hole physics.[12][13][14]
