Matias Zaldarriaga is a theoretical astrophysicists recognized for his work in cosmology. He is known in particular for his contributions to our understanding of the early universe, particle astrophysics, and cosmology as a probe of fundamental physics. Much of his work centers on understanding the clues about the earliest moments of our universe encoded in the Cosmic Microwave Background, the faint glow of radiation generated by the Big Bang, and in the distribution of matter in the late universe. Zaldarriaga grew up in Buenos Aires, Argentina. He graduated from the University of Buenos Aires in 1994 with a degree of Licenciado en Ciencias Fisicas and obtained his PhD degree in 1998 from the Massachusetts Institute of Technology. He was a postdoctoral fellow at the Institute for Advanced Study in Princeton, NJ and a faculty member at New York University and Harvard University before joining the faculty at the Institute for Advanced Study in 2009.

Research Interests

Matias Zaldarriaga is interested in a wide range of topics in theoretical cosmology and astrophysics. He is interested in understanding the earliest instants in the history of the Universe and in developing the necessary tools to interpret observations of the Cosmic Microwave Background and of the distribution of matter across cosmic history.
