Simons Postdoctoral Research Associate in Gravitation and Cosmology

The Physics Department at Princeton University expects to have a postdoctoral position for a candidate working at the interface between theoretical cosmology and general relativity, nominally starting September 1, 2020. The initial appointment will be for one year, renewable up to three years contingent on continued funding and satisfactory performance. A PhD in Physics, Astrophysics, Mathematics, or a related area is required.
The postdoctoral fellow will be supported by a Simons Foundation targeted grant under the Initiative entitled New Directions in Gravitational Theory and Cosmology: Cosmological Bounces & Bouncing Cosmologies (see http://bouncingcosmology.com). The fellow will be part of an international collaboration pursuing a broad range of fundamental problems in cosmology and general relativity using a spectrum of techniques that include analytical and numerical relativity and field theory.  Interested candidates with a wide range of backgrounds, which might include cosmology, general relativity or high energy physics, will be considered. 

Applications will begin to be reviewed on December 1, 2019. Under the link below, you may upload a recent CV, research statement and contact information for three referees who will be solicited to provide letters of support.

For more information please contact Paul Steinhardt at steinh@princeton.edu.

Princeton University is an equal opportunity employer and all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability status, protected veteran status, or any other characteristic protected by law. This position is subject to the University’s background check policy.

Simons Foundation announces new Targeted Grant
New Directions in Cosmology and Gravitational Theory: Cosmological Bounces and Bouncing Cosmologies

Today the Simons Foundation announced the award of a new Targeted Grant to Principal Investigators Anna Ijjas (MPI-AEI) and Paul Steinhardt (Princeton).

The goal is to develop, explore and test theories of the origin, evolution and future of the universe that challenge the standard view that the universe began with a big bang about 14 billion years ago. According to this new paradigm, what has been long believed to be a beginning was actually a transition — known as a ‘bounce’ — from a preceding period of contraction to the current period of expansion. The observed properties of the universe today trace back to events that occurred during the period of contraction and the bounce. In some of the most interesting versions, space-time exists eternally through regular cycles of expansion, contraction and bounce, driven by the same fields that are responsible for dark energy. Significant progress has been made in the last few years in identifying the basic elements of this picture, and the grant enables its full development.

Simons Origins of the Universe Collaboration announced

Today the Simons Foundation announced the new Origins of the Universe Initiative. The Foundation has assembled an international group of theoretical physicists to tackle one of the biggest unsolved mysteries in science: What exactly went down at the dawn of the universe around 13.8 billion years ago.

The Cosmological Bounces and Bouncing Cosmologies program is a key component.
