Prof. Kelly's research focuses on the fields of fundamental particle physics and cosmology, attempting to understand the basic properties of matter and how those interactions have driven the evolution of the universe to the present day. Specifically, Kelly studies neutrinos, one such fundamental particle that's arguably the least understood in nature, and how experiments based on earth and beyond can help us solve some outstanding mysteries in particle physics. He also explores theoretical ideas surrounding dark matter in the universe, especially considering the possibility that the mysteries surrounding neutrino and dark matter physics may be intrinsically connected.
