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变是当代宇宙学的主要目标之一。星系是包含恒星，气体，灰尘和大量暗物质的多样化复杂系统。暗物质是未观察到的质量，其存在是由于其对周围材料的重力影响推断出来的。但是，暗物质的详细特性仍然难以捉摸。我有兴趣了解星系（颜色，形状，出色的含量）的观察到的特性取决于周围的暗物质的分布。
