18.03.2026 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. Read more
