The Daan family was highly interested in biology and undertook enterprises in this field, such as investigating the ecology of reptiles in the Mediterranean area. As a consequence of this interest, Serge studied biology at the University of Amsterdam.

Serge Daan took the initiative to set up and coordinate the top-master program in Behavioural and Cognitive Neurosciences at the University of Groningen, the Netherlands.

The ruler is awarded each time by the previous winner to a new winner, who is selected because he or she is doing chronobiological research with a different technique in a different species than the previous winner.

Serge Daan held many offices in academia. He was member of the board of Earth and Life
Sciences of NWO â the Netherlands Organisation for Scientific Research (1997â2002), and chairman of the NWO program Evolution and Behaviour (2002â2009). He was president of the Dutch Society for Behavioural Biology

However, this notion was inconsistent with observations of the timing of sleep in human

Beersma, developed a model which convincingly explained the observations. It was called the two-process model of sleep regulation and explained human sleep regulation in terms of two key processes: a circadian pacemaker, and a homeostatic drive to sleep that increases during wake and decreases

Working with
Pittendrigh, Daan developed many of the theoretical foundations for understanding the dynamics of circadian oscillators. Many other studies have followed, shifting the focus from behavioural black box models to testable hypotheses about underlying molecular mechanisms.

Apart from daily alternations in the environment, there are substantial seasonal variations that animals must adapt to across the year. Working with Drent, Daan showed that one strategy used to deal with seasonal changes is to adjust the number and even sex of offspring.
