With big telescopes we can observe billions of galaxies across most part of the sky. If we mark each galaxy by a point we can see a weblike pattern that we call the cosmic web. This weblike pattern looks different from how matter is distributed at early times. I am trying to understand how matter clustered over time. The formation of galaxies is a hard problem, but we know that there must be dark matter to help them form. I model dark matter because it’s a lot easier to describe, but we cannot observe it directly. This is why I also describe where galaxies tend to live in the dark matter. Putting both things together, we can compare our theory model with observations to figure out what are the ingredients of our Universe.

I teach on two days a week, currently Einstein’s Theory of General Relativity which describes how matter and light behaves in strong gravitational fields. I have regular meetings to help my junior group members do their research and exchange ideas. I work in many international teams of different sizes, so we often use text chat and video conferences to coordinate.
