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.
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. Most recently, he and his collaborators discovered a novel signature of primordial nongaussianity (departures from nongaussianity in the initial distribution of matter in the universe); the signature affects the distribution of galaxies today, and enables many times more precise measurements of primordial nongaussianity than previously thought possible.
