The Pittendrigh-Aschoff Lecture 2024.

Chronobiology is one of the broadest disciplines in science - we can study and apply this system from molecules to shiftwork, from individuals to populations, from physiology to psychology, from mechanisms to medicine. Since I have an aversion against thinking in boxes, chronobiology was the only discipline I could faithfully live in for the past 55 years, giving me the privilege to witness its epitaxy from its pioneers to circadian medicine. I have tackled chronobiological questions with many different methods, but by far my favorite tool to understand are concepts.
