Introduction:

Gravitational lensing is one of the most powerful tools in the field of Astrophysics and Cosmology. It probes matter distributions at all scales from stars to galaxies to large scale structures in the Universe. Such studies not only help us to unveil the physics of the formation and evolution of cosmic structures, but also provide us with crucial clues to the understanding of many fundamental physics questions, such as the nature of the dark sectors of the Universe as well as gravity. My main research field is using gravitational lensing as a tool to probe galaxy evolution and dark matter physics, in particular through numerical methods and computer simulations in order to tackle theoretical questions on galaxy evolution, test systematics of existing obervational methods, as well as develope novel modelling methods to be used to in upcoming galaxy surveys.
