Galaxy groups and clusters are some of the largest gravitationally bound objects in the observable universe. The hot intracluster gas component emits brightly in X-ray which enables us to probe them with telescopes such as Chandra and XMM-newton. These systems have a large dark matter content (typically 85%) and are so massive that their gravitational influence can bend the light emitted by background galaxy sources. Using these properties and others, galaxy clusters are essentially cosmic laboratories that we can use to understand the Universe we live in. Accurate mass measurements of groups and clusters in a diverse range of redshifts, will help us to understand the origin and fate of the Universe and the structural evolution.

Currently I am working with cluster data from XMM-XXL/LSS surveys and CFHTLenS. My work involves deriving cluster masses from various methods including: X-ray luminosity growth curves, scaling relations and shear measurements. This is important for cosmology and allows us to have a better understanding of cluster physics.

I am the founder of the for the student conference IMPACT (www.sr.bham.ac.uk/IMPACT) and was a member of the scientific organising committee until Jan 2016. This quarterly conference unites the local universities in the Midlands Physics Alliance with the aim of promoting a pressure free environment for PhD students to practice giving talks, present research posters and engage in discussions.
