Michael Rosbash

Michael Rosbash is a renowned American biologist who, along with colleagues, discovered the molecular mechanisms underlying the circadian rhythm—the body's internal 24-hour clock that regulates sleep, wakefulness, and other biological processes. His research revealed how specific genes and proteins create these daily biological cycles. In 2017, he received the Nobel Prize in Physiology or Medicine for this groundbreaking work, which has deepened our understanding of biological timing and its impact on health and behavior.
