Reader & Royal Society University Research Fellow at the University of Edinburgh
Previously held research positions at the University of Edinburgh, Durham University, and the University of Pennsylvania, including a Marie Curie Early Stage Training Fellowship at Durham during doctoral studies.


Research:


Physical cosmology -- exploring the complexity of our Universe in search of its underlying coherence. Research topics include testing dark energy and theories of gravity, large-scale structure, the cosmic web: voids, filaments, and galaxy clusters; redshift-space distortions, gravitational redshift and weak gravitational lensing; secondary effects of the cosmic microwave background such as the integrated Sachs-Wolfe & Rees-Sciama effects, and the Sunyaev–Zeldovich effect.
