Matias Zaldarriaga is a physicist who has made many influential and creative contributions to our understanding of the early universe, particle astrophysics, and cosmology as a probe of fundamental physics.
Much of his work centres 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. His recent research has focused on intergalactic hydrogen gas in the early universe. He is at the forefront of developing machinery to study this gas, using the spectral line from neutral hydrogen at 21-cm wavelength.
