Astroparticle physics and cosmology is the fast growing interface between particle physics and astrophysics. This exciting new area involves using the Universe as a laboratory to study fundamental physics.

Dark Matter

We are particularly interested in Weakly Interacting Massive Particles (WIMPs). We study techniques for detecting WIMPs in specific fundamental theories (based on the idea of grand and string unification) including constraints from particle physics colliders and realistic modeling of the Milky Way's dark matter halo. We work closely with the experimental particle physics group which is part of the UK Dark Matter Collaboration, a world leader in this area.

Particle theory and phenomenology

In related research we are studying ways of testing other predictions of supersymmetry and other models of "new physics" at particle physics colliders, like the Large Hadron Collider at CERN, as well as in non-collider experiments. Our comprehensive approach includes inter-related issues such as electroweak symmetry breaking, the Higgs mass spectra, implications of b--> s gamma, the anomalous magnetic moment of the muon, CP and flavour violation.

Early universe cosmology

We are interested in how the presence of extra dimensions, in the context of brane world scenarios, affects the production and evolution of cosmological perturbations. In particular anisotropies in the Cosmic Microwave Background Radiation (CMB) provide strong constraints on brane world model building. We are also interested in testing the properties of Dark Energy with cosmological observations.


We are interested in the physics of both classical and quantum black holes, with a particular focus on the formation and evaporation of brane world or higher-dimensional black holes. We are also interested in quantum gravity phenomology and modeling quantum black holes in TeV-scale quantum gravity scenarios.
