Understanding the formation and evolution of galaxies is one of the primary objectives of contemporary cosmology. Galaxies are diverse complex systems containing stars, gas, dust and vast amounts of dark matter. Dark matter is unobserved mass whose presence is deduced by its gravitational influence on surrounding material; however the detailed properties of dark matter remain elusive. I am interested in understanding how the observed properties of galaxies (colours, shapes, stellar content) depend on the distribution of dark matter that surrounds them.

了解星系的形成和演化是当代宇宙学的主要目标之一。星系是多种多样的复杂系统，包含恒星、气体、尘埃和大量暗物质。暗物质是一种无法观测到的物质，它的存在是通过它对周围物质的引力影响推断出来的；然而，暗物质的详细性质仍然难以捉摸。我感兴趣的是了解观察到的星系的特性（颜色、形状、恒星含量）是如何依赖于它们周围暗物质的分布的。
