Till Roenneberg

Till Roenneberg is a German chronobiologist who studies biological rhythms, particularly the human sleep-wake cycle. He examines how our internal clocks, or circadian rhythms, influence sleep patterns, health, and behavior. His research helps explain why people have different chronotypes—some are morning larks, others night owls—and how modern lifestyles and artificial light affect our natural rhythms. Roenneberg's work aims to improve understanding of sleep health and optimize daily schedules to better align with our biological clocks, promoting better well-being and overall health.
