Research Themes

The Cosmology and Gravity Group studies the origin, evolution and large-scale structure of the Universe, and tests the gravitational physics that underpins modern cosmology.

Our main research themes are:

• modified theories of gravity, including f(R), f(T) and f(Q) models

• cosmological perturbations and large-scale structure formation

• interacting dark energy and dark matter

• observational cosmology and tensions in H₀, S₈ and related probes

• black holes, gravitational lensing and strong-field gravity

• dynamical systems in cosmology

• cosmic magnetism, reionisation and SKA-era science

• scientific computing, simulations and statistical inference

A current cross-cutting focus is the Cosmological Consistency Triangle, which tests cosmological models jointly against background expansion, growth amplitude and a theory-specific third observable. The group combines theoretical work with emerging observational data, and brings together staff, visiting researchers, postdoctoral fellows and postgraduate students.
