Till Roenneberg (born May 4, 1953) is a professor of chronobiology at the Institute of Medical Psychology at Ludwig-Maximilian University (LMU) in Munich, Germany. Roenneberg, in collaboration with Martha Merrow, explores the impact of light on human circadian rhythms, focusing on aspects such as chronotypes and social jet lag in relation to health benefits.
Roenneberg was born in Munich, Germany. He began working with Jürgen Aschoff at the age of 17.
Roenneberg attended both the University College London and Ludwig Maximilian University of Munich where he began by studying physics. He switched to medicine in order to focus on the science of the human body, but ended up studying biology. As a postdoctoral fellow, he studied again under Jürgen Aschoff, studying annual rhythms in the body, then moved to the United States to study the cellular basis of biological clocks under Woody Hastings at Harvard University.
In 1991, he began the tradition of giving the Aschoff’s Ruler prize to a chronobiologist who has advanced the field.
He is currently the vice-chair of the Institute for Medical Psychology of the Ludwig Maximilian University of Munich, the head of the Centre for Chronobiology, the president-elect of the European Biological Rhythms Society, the president of the World Federation of Societies for Chronobiology, and a member of the Senior Common Room of Brasenose College, University of Oxford. From 2005 to 2010 he was the coordinator of "EUCLOCK" and coordinator of the Daimler-Benz-Foundation network "ClockWORK", and from 2010 to 2012 was the member at large of the Society for Research of Biological Rhythms
Aside from human chronobiology, Roenneberg has significantly contributed to other aspects of the chronobiology field. He has done extensive work on dinoflagellates, a unicellular organism, and has been able to show that even this simple organism is capable of possessing two independent rhythms, providing evidence that a single cell can have two different oscillators. In addition, his work on dinoflagellates has been able to show that these two independent oscillators differ to a significant extent in that they respond differently when treated with various light pulses. They found that the two oscillators have varying sensitivities to different types of light. The B-oscillator is most sensitive to blue light while the A oscillator is sensitive to both blue and red light.
