LATEST RESEARCH HIGHLIGHT
Here is our latest CLASH result and in collaboration with members of the Planck team. In this paper we use the lensing-derived masses of CLASH clusters published in Merten et al. (2015) to determine the mass scale of clusters detected via the thermal Sunyaev Zel'dovich effect. A concise Bayesian analysis framework properly accounts for the CLASH selection function and potential systematic effects. The analysis finds a bias of 1-b_sz = 0.73 +/- 0.10 between true cluster masses and the Planck SZ mass proxy. This result is in good agreement with other studies and goes a long way towards reconciling the mild tension between predictions from the Planck primary CMB analysis and Planck cluster counts (see figure below).

As a Marie Curie Fellow at the University of Oxford's Department of Physics, in the field of Cosmology, I am interested in the composition and evolution of the Universe as a whole. More specifically, my goal is to understand the elusive dark matter and dark energy via the study of cosmic structure formation.
The main tool used in my research is gravitational lensing, the deflection of light rays along their path in the presence of massive structures. The most massive of these structures are clusters of galaxies, another focus of my research.
