Galaxies and clusters of galaxies reveal the large-scale structure of the Universe. Their distribution on the sky is determined by the cosmological model describing our Universe and the physical processes by which normal, or baryonic, matter forms stars and hot gas and thus becomes visible. By determining the statistical distribution of galaxies and clusters on the sky, and by understanding the physics of star formation and gas evolution within them, one can determine the salient properties of the cosmological model, e.g. expansion rate, the amount of matter, both baryonic and dark, in addition to the nature of dark energy. I am a leading member of the Ultimate XMM Extra-galactic survey (XXL), a large, multi-wavelength survey of galaxy clusters built upon the largest single XMM-Newton project ever awarded. Working both on this survey and it predecessor, the XMM-LSS survey, I have developed a strong track record for myself and my HQP at performing high-impact science within a leading international collaboration. My interests and those of my HQP centre upon the discovery and scientific analysis of very distant galaxy clusters and the evolution of galaxies within clusters over large intervals of cosmic time.

星系和星系团揭示了宇宙的大尺度结构。它们在天空中的分布取决于描述我们宇宙的宇宙学模型，以及正常物质或重子物质形成恒星和热气并因此变得可见的物理过程。通过确定星系和星系团在天空中的统计分布，并通过理解星星形成和气体演化的物理学，人们可以确定宇宙学模型的突出属性，例如膨胀率，物质的数量，重子和暗物质，以及暗能量的性质。 我是终极XMM河外星系调查（XXL）的主要成员，这是一项大型、多波长的星系团调查，建立在有史以来最大的单个XMM-Newton项目的基础上。在这项调查及其前身XMM-LSS调查中，我为自己和我的HQP在领先的国际合作中执行高影响力科学方面建立了良好的记录。我和我的HQP的兴趣集中在发现和科学分析非常遥远的星系团和星系团内的星系演化在宇宙时间的大间隔。
