Professor Nelson's research program is centered around galaxy formation and evolution: understanding how the Universe evolved from its uniform state shortly after the Big Bang to the rich diversity of galaxies we see today. She uses cutting-edge observational techniques and cosmological hydrodynamical simulations to understand the physical processes that drive the the structural and kinematic evolution of galaxies and how star formation is regulated. These two fundamental processes in turn provide the strong constraints on theoretical models of galaxy formation. She is heavily involved in the newly launched James Webb Space Telescope which will act as time machine to see the formation of the first galaxies near the beginning of cosmic history.
