Observational cosmology is an attempt to understand the processes which initiated the universe we live in, and how the rich and complex structure in the present-day universe formed and evolved. My research focuses on studying both the fundamental physics of cosmology via the Cosmic Microwave Background (CMB) and measurements of structure on very large scales, down to the details of galaxy evolution and the complex physics which manifests on small scales. There are many unanswered questions, starting from how the primordial density fluctuations in the very early universe inflated to produce the observed distribution of structure and galaxies, all the way to how environment drives galaxy evolution. Studying the Sub-millimetre Galaxies (SMGs) in particular in the distant universe gives us insight into the peak epoch in which massive galaxies were forming the bulk of their stars. This leads to a host of questions, such as whether massive galaxies form in a single burst of star formation or is their growth extended over time.

观察性宇宙学是一种尝试理解启动我们所生活宇宙的过程，以及当今宇宙中富裕和复杂的结构如何形成和发展。我的研究重点是通过宇宙微波背景（CMB）研究宇宙学的基本物理学，并在非常大的尺度上研究结构的测量，直到星系进化的细节和在小尺度上表现出的复杂物理学的细节。从早期宇宙中的原始密度波动膨胀到产生观察到的结构和星系的分布到环境如何驱动银河系进化的方式，有许多未解决的问题，从早期宇宙中的原始密度波动如何膨胀。特别是在遥远的宇宙中研究亚毫米的星系（SMG），使我们深入了解了巨大的星系形成大部分恒星的峰值。这导致了许多问题，例如，巨大的星系是在单一恒星形成中形成还是随着时间的推移而延长的。
