Role

• Senior Lecturer
• Research Placement Course Convenor
• Undergraduate Careers Tutor

I am a member of the Sussex Astronomy Centre. I use multi-wavelength observations of clusters of galaxies to test theories of the cosmological model and of structure formation. I am PI of the multi-national XMM Cluster Survey project and a member of the Dark Energy Survey; cluster working group. My research covers the following topics:

• Observational Cosmology
• Extra-galactic Surveys
• Clusters of Galaxies
• X-ray Astronomy
• The Sunyaev'Zel'dovich Effect
• Search for Warm Dark Matter

• Cosmology (Level 3, F3078)
• Cosmology (Level M, 863F3)
• Astronomy Research Skills (Observational Cosmology Modules 1 and 2)
• DPhil project supervision
• MSc project supervision
• Research Placement supervision
• Undergraduate Final Year project supervision
