Postdoctoral positions studying sleep using zebrafish (Prober Lab)
Postdoctoral positions are available to study genetic and neuronal mechanisms that regulate sleep in the lab of David Prober at the California Institute of Technology.
Humans devote a third of their lives to sleep, sleep disorders are pervasive in modern societies, and sleep-like states are conserved throughout evolution, yet the regulation and function of sleep remain among the most enduring mysteries in biology. The Prober lab is taking a new approach to this problem by using zebrafish, a vertebrate whose brain is anatomically and molecularly similar to that of mammals. Zebrafish offer several advantages for sleep research, including optical transparency that allows for whole-brain calcium imaging and non-invasive optogenetic manipulations, small size that facilitates large-scale behavioral assays, and a diurnal pattern of sleep/wake states. Through the use of high-throughput screens and candidate-based approaches, the Prober lab has shown that zebrafish share genetic and neuronal mechanisms of sleep regulation with mammals, and has also identified novel mechanisms that regulate sleep. Positions are available to study genetic and neuronal circuits that regulate sleep, perform whole-brain analysis of neuronal activity during sleep and wake states, and explore interactions between circadian and homeostatic sleep control. These projects offer opportunities to develop skills in developmental and behavioral neuroscience, genetics, molecular biology and imaging approaches.
The following papers illustrate our approach to sleep research.
