Berian’s research is in the fields of observational and theoretical cosmology; particularly, statistics of large-scale structure, galaxy formation and evolution, type Ia supernovae and the foundations of relativistic cosmology.
Since September 2009, he has held a Sophie & Tycho Brahe Fellowship in Astrophysics jointly between UC Berkeley and the Dark Cosmology Centre in Copenhagen, running a research programme in Cosmic Evolution and Large-scale Structure between the two institutions. This work develops the relationship between the structures formed by gravity—galaxies, clusters, voids—and fundamental features of the expanding Universe.
He plays classical guitar and likes music by contemporary composers.
