Academic Interests

I want to know what the universe is made of. The standard model of particle physics is a very successful theory when it comes to describing the fundamental particles and the forces binding them together. However, it does not explain dark matter and the smallest particles, the neutrinos. Using cosmological measurements such as galaxy surveys and primordial chemical abundances, I try to uncover some of the secrets of dark matter and neutrinos.
