Irving Zucker

Irving Zucker is a Professor of the Graduate School at the University of California, Berkeley, affiliated with the Department of Psychology. His research focuses on biological rhythms, seasonal reproductive cycles, and photoperiodism in mammals, particularly rodents. He directs the Biological Rhythms Laboratory, exploring how circadian and circannual pacemakers regulate physiology and behavior, including hibernation, energy balance, and temperature regulation.

Education: Ph.D. in Psychology from the University of Chicago. His work emphasizes interdisciplinary approaches, combining field and laboratory studies to understand environmental influences on neuroendocrine systems. Graduate students collaborate on projects involving melatonin signaling, suprachiasmatic nucleus function, and the impacts of circadian disruption on development.

Research highlights include groundbreaking studies on sex differences in biomedical research, advocating for inclusive preclinical testing, and uncovering mechanisms linking seasonal light cycles to reproductive timing. Zucker’s publications address topics like ultradian rhythms, pharmacokinetic variability in women, and the physiological consequences of maternal circadian disruption.
