Priyamvada Natarajan is a professor at the Department of Astronomy and Physics at Yale. She is a theoretical astrophysicist interested in cosmology, gravitational lensing, and black hole physics. One of her research projects involves mapping the detailed distribution of dark matter in the universe exploiting the bending of light en-route to us from distant galaxies. She also works on deriving and understanding the mass assembly history of black holes over cosmic time. She has proposed the formation of an early population of massive black holes—direct collapse black holes—and their observational consequences and detectability. Recipient of many awards and honors for her research including the Guggenheim and Radcliffe Fellowships, Natarajan also holds the Sophie and Tycho Brahe Professorship at the Dark Cosmology Center in Copenhagen and an honorary professorship for life at Delhi University, India. Her first book Mapping the Heavens was published in 2016.
