Matias Zaldarriaga was born in Buenos Aires, Argentina in 1971 and graduated with an undergraduate degree in physics from the University of Buenos Aires in 1994. He then earned a Ph. D. in physics from MIT in 1998. Dr. Zadalarriaga was a post doc at the Institute of Advanced Study before starting work at New York University as an assistant professor in 2001. But in 2003 he moved to Harvard University.

Matias Zaldarriaga's research focuses on questions of the structure and nature of the early universe. He has developed a software package that is used to interpret the cosmic microwave background (CMB) and the results of his work have influenced the design of new telescopes. He has also shown how subtle differences in the CMB can be used to interpret the early nature of the universe.

Dr. Zaldarriaga was selected as a Packard Fellow in 2001 and a MacArthur Fellow in 2006. A brief essay of his work appears in the May 5, 2005 Harvard Gazette which can be found online at http://www.news.harvard.edu/gazette/2005/05.05/03-zalda.html.
