Jeffrey C. Hall
Jeffrey C. Hall is an American geneticist known for his groundbreaking research on the molecular mechanisms controlling biological rhythms, particularly circadian clocks that regulate sleep and activity cycles. His work, along with colleagues Michael Rosbash and Michael Young, uncovered how specific genes and proteins generate these natural 24-hour rhythms in organisms like fruit flies, providing insights into sleep patterns and health. Their discoveries have broad implications for understanding human sleep disorders, jet lag, and overall biological timing, earning Hall the Nobel Prize in Physiology or Medicine in 2017.
