description Jeffrey Hall Overview
Jeffrey Hall is an American geneticist who conducted much of his circadian rhythm research at Brandeis University. He shared the 2017 Nobel Prize in Physiology or Medicine with Michael Rosbash and Michael Young for discoveries of molecular mechanisms controlling biological clocks. Hall and Rosbash collaborated to show that the period gene in Drosophila produces the PER protein in rhythmic oscillations tied to the day-night cycle. Their work established that circadian rhythms arise from a self-regulating transcription-translation feedback loop within cells.
help Jeffrey Hall FAQ
At which university did Jeffrey Hall conduct his circadian rhythm research?
Jeffrey Hall conducted much of his foundational circadian rhythm research at Brandeis University. He worked closely with his colleague Michael Rosbash in their laboratories there.
What specific mechanism did Jeffrey Hall identify to win the Nobel Prize?
Hall and his colleagues discovered how the period gene regulates the molecular mechanisms controlling the circadian rhythm. They showed that the protein encoded by this gene accumulates during the night and degrades during the day.
With whom did Jeffrey Hall share the 2017 Nobel Prize in Physiology or Medicine?
He shared the 2017 Nobel Prize with Michael Rosbash, his colleague at Brandeis, and Michael Young of Rockefeller University. Their combined work explained the internal biological clock that helps organisms adapt to the Earth's revolutions.
What organism did Jeffrey Hall use for his genetic studies?
Hall, alongside Rosbash, performed their Nobel-winning research using the fruit fly (Drosophila melanogaster). By isolating and mutating the period gene in fruit flies, they were able to observe changes in their sleep-wake cycles.
