Hello! I'm Céline Gouin,
postdoctoral research fellow at KIAS in Korea

I am working on the large scale structures of the Universe by using both hydrodynamical cosmological simulations and large galaxy survey. I am focused on probing galaxy cluster environments, where filaments connect to clusters which are the nodes of the underlying cosmic web.
