Dr. Barbara Demmig-Adams is a professor of distinction in the Department of Ecology & Evolutionary Biology at the University of Colorado, Boulder, USA. She is a Packard Fellow and member of Leopoldina (joint National Academies of Sciences of Germany, Austria and Switzerland). Her plant research focuses on the roles of the carotenoid zeaxanthin in the photoprotection of photosynthesis and places mechanistic information into the context of different photosynthetic organisms and diverse environments. Her recent work in plant biology uses insight from plant eco-physiology to co-optimize the nutritional quality and sustainability of novel food systems. Together with her students, she also synthesizes the literature on the effects of nutrition and other aspects of lifestyle medicine on human health and wellness.
