From 1998–2000, Huberman worked in the laboratory of Irving Zucker and with Marc Breedlove, at University of California, Berkeley, as part of a team that defined how early androgen exposure impacts development,[11] and he performed the first experiments defining the structure of binocular visual pathways that set the circadian clock in the hypothalamus.[12] From 2000-2004, working as a Ph.D. student in the laboratory of Barbara Chapman at the Center for Neuroscience at the University of California, Davis, he discovered that neural activity and axon guidance molecules work in concert to ensure proper wiring of binocular maps in the brain.[13][14][15] Huberman was a Helen Hay Whitney postdoctoral fellow researcher in the laboratory of Ben A. Barres from 2005 to 2010.
