[math-ias] 2021 Gruber Cosmology Prize

[Robbert Dijkgraaf]

Dear Colleagues and Friends, 



Please join me in congratulating Matias Zaldarriaga, who was named a recipient of the 2021 Gruber Cosmology Prize, which honors contributions that have been essential to the development of this field of research over the last twenty-five years. 



Matias shares the honor with Marc Kamionkowski—a past Member in the School (1991–95) currently at Johns Hopkins University—and Uroš Seljak of University of California at Berkeley and Lawrence Berkeley National Laboratory. 



Along with Kamionkowski and Seljak, Matias has helped revolutionize the way in which researchers are able to analyze the cosmic background radiation, unlocking many deep mysteries of the universe. The concepts outlined in two independent but simultaneous papers ( [ https://journals.aps.org/prd/abstract/10.1103/PhysRevD.55.7368 | Kamionkowski, 1997 ] ) and ( [ https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.78.2054 | Seljak and Zaldarriaga, 1997 ] ), provide a mathematical means to infer the history of the Universe all the way back to the first fraction of a fraction of a second of the universe’s existence. 



Matias first came to the Institute as a Member (1998–2001 and 2001–02) and was appointed to the Faculty in 2009. His work has touched nearly every major area of cosmology research, including the early expansion of the universe, its age and composition, and primordial gravitational waves. 



Once again, it is my pleasure to recognize Matias and his colleagues for their incredible contributions to this field.
