Arjun Dey

Arjun Dey began exploring the universe at 15 years of age as an amateur astronomer and telescope builder. He received his PhD from UC Berkeley and is now an astronomer at NOIRLab, the US national center for ground-based optical and infrared astronomy. A recipient of Fellowships from the Radcliffe Institute and Guggenheim Foundation, Arjun’s research focuses on how galaxies form and evolve, and what they reveal about the invisible contents of the universe: dark matter and dark energy. He is a key member of the Dark Energy Spectroscopic Instrument survey project, which aims to measure the expansion history of the universe, explore the nature of dark energy, investigate the evolution of galaxies, and study the structure and fossil history of the Milky Way.
