Physics of Cosmic Acceleration

The physics underlying the accelerated expansion of the universe is unknown. Most of my recent research aims to explore various explanations. Examples include: a dynamical scalar field, quintessence; new gravitational phenomena; and alternative scenarios that dispense with dark energy altogether. My students and I develop these ideas, to make predictions for comparison with observations and experiments.
