David Weinberg, Distinguished University Professor and Chair of the Department of Astronomy, was named in Clarivate's 2021 list of Highly Cited Researchers. This recognition is due to the fact that he has had multiple publications that have been highly cited in the last decade, pertaining to his studies in the large-scale structure of the universe, dark energy and dark matter, the formation and evolution of galaxies and quasars, the intergalactic medium, and the origin of the chemical elements. Fewer than 0.1% of the world's researchers received this distinction in 2021.
