David Lincoln Rabinowitz (born 1960) is a researcher at Yale University. He has built CCD cameras and software for the detection of near-Earth asteroids and Kuiper Belt Objects, and his research has helped reduce the assumed number of near-Earth asteroids larger than 1 km by half, from 1,000–2,000 to 500–1,000 He has also assisted in the detection of distant solar system objects, supernovae, and quasars, thereby helping to understand the origin and evolution of the solar system and the dark energy driving the accelerated expansion of the universe.
