Davide Barreca is an Assistant Professor of biochemistry at the University of Messina. He is specialized in isolation, identification, and analysis of antioxidant and biological function of flavonoids present in natural matrices and their interaction with biological macromolecules. He received his Ph.D. degree in 2006 and postdoctoral fellowship in 2010 from the University of Messina, focusing the topic of its studies on the antioxidant and prooxidant activity of some poliphenols of natural source on cells culture. Most of his research projects concentrate on separation and identification of unknown flavonoids, structural-activity elucidation, and biochemical analysis of their health promoting properties, exploring their suitable employment in pharmaceutical and cosmetic industry, as well as nutraceutical food supplements. He is author of 72 papers in peer-reviewed journals, 15 chapters in books, and 60 conference proceedings. He is also author of a university textbook on biochemistry of nutrition, reviewer in 20 international scientific journals, and evaluator of research proposals in national and European calls.
