Professor Huterer's principal interest is in understanding the nature and origin of "dark energy", a mysterious component that makes up about two thirds of the universe's energy and also causes its acceleration. The physical mechanism that powers the recently discovered acceleration of the universe is one of the great mysteries of modern physics and astronomy. Professor Huterer uses cosmological probes to study the properties of dark energy, and these include measurements of distances to type Ia supernovae, mapping the growth and evolution of the large-scale structure in the universe, and gravitational lensing. He is a member of the Supernova/Acceleration Probe (SNAP) collaboration, a team that plans to provide definitive constraints on properties of dark energy using a new space telescope custom-built for this purpose, in which Michigan physicists are a major partner.
Professor Huterer is also actively involved in studying the isotropy of the universe and the mathematical distribution of primordial inhomogeneities that seeded structures observed on the sky today. Recently, he and his collaborators discovered unexpected alignments in the distribution of cosmic microwave background temperature anisotropies on large angular scales, and proposed a novel method to study violations of statistical isotropy.
