  quantum-cosmology phenomenology.
  * Idea: Issues studied
    include the possible emergence of an inflationary epoch from a quantum
    gravity instanton–tunneling solution or a bounce, and the predictions
    for the perturbation spectrum in various approaches to quantum gravity.
  * Motivation:
    Inflation has been used to try to avoid the initial Big-Bang singularity by giving bounce solutions.
