Dr Sarah E. I.
Bosman

I'm a cosmologist @ UCL, London.

My research spans the first billion years of the Universe - when the first stars, first galaxies and supermassive black holes formed, and destroyed the neutral hydrogen which filled the Universe in what is called reionisation.

I am mostly an observational cosmologist and have observed early galaxies and quasars with many observatories around the world, both remotely and in person. I dabble in equations and numerical simulations on occasion.
