Etienne Challet

Board Member
Etienne Challet received his Ph.D. degree from University of Strasbourg (France) in 1996. He then completed a 2-year postdoctoral fellowship at Northwestern University (USA), and a 1-year postdoctoral fellowship at Free University of Brussels (Belgium). In 2000, he has been recruited as a Tenured Researcher at the National Center for Scientific Research (CNRS) in Strasbourg. Since 2005 he has been leading a CNRS research team at University of Strasbourg. He has been promoted as director of research in 2007 (senior grade in 2019).

His research areas include chronobiology, neuroscience, neuroendocrinology and nutrition. More precisely, he investigates functioning of the cerebral clocks and their resetting by feeding, metabolic and arousing signals with an integrative approach combining molecular biology and comparative physiology. His main goal is to identify the pathways through which the brain clocks control the rhythmicity of physiological processes, such as the daily feeding/fasting cycle and meal anticipation, and in turn, how the brain clocks are regulated by feeding and arousing cues in both noctunral and diurnal animal models.

His 140 peer-reviewed publications in scientific journals, including 120 original articles (e.g. Journal of Neuroscience, Current Biology, FASEB journal, Neuropsychopharmacology), and 20 reviews (e.g. Nature Reviews Endocrinology, Endocrine Reviews, Neuroscience & Biobehavioral Reviews), have been cited close to 5000 times (h-index 40, Web of Science).
