Professor Pober works in the field of "21 cm cosmology" -- a program of research to observe neutral hydrogen from the early universe through its hyperfine 21 cm emission line. His interests include both the development of new radio astronomy techniques to make these observations possible, and the physics of early universe galaxy formation and cosmology that they probe. He is a member of the PAPER, MWA, and HERA experiments. He arrived at Brown in January 2016; prior to that he was a postdoctoral fellow at the University of Washington. He received his PhD from UC Berkeley in 2013.
