Gravitational Wave Cosmology: From Theory to Experiments in Swansea

This PhD studentship offers the chance to develop an ambitious research project at the interface of theory and experiment in gravitational-wave physics and cosmology. Working closely with experienced faculty, the student will explore fundamental questions about the Early Universe and the dark sector, which together shape most of the cosmos we observe today. Many of the most compelling models in these areas predict stochastic backgrounds of gravitational waves—signals that may be detected by current and next-generation experiments. Applcation deadline: April 6th 2026.

The successful candidate will:

  • Develop and test theoretical models of the Early Universe and dark sector physics.
  • Make quantitative predictions for gravitational-wave signals.
  • Connect theory with observational or simulated data from leading international collaborations.

Through active mentorship and collaboration, the student will have the opportunity to engage with major international projects, including Laser Interferometer Space Antenna (LISA), Einstein Telescope, Square Kilometre Array Observatory (SKAO), and NANOGrav. This involvement will enable the student to become part of vibrant, international research teams at the forefront of discovery.

This is an outstanding opportunity for a motivated student to contribute to some of the most exciting questions in modern physics, gain high-level research training, and build an international scientific profile in a rapidly advancing field.
