Research Interests

Dr. Ottaviani’s research focuses on understanding the beneficial effects of dietary flavanols and procyanidins on cardiovascular health. His interests include i) the characterization of absorption, distribution, metabolism and excretion of flavanols and procyanidins in humans and other species; ii) the development and validation of methodologies capable of quantifying flavanols and procyandins in different biological samples, and iii) elucidating the biochemical mechanisms behind the vascular effects mediated by flavanol and procyanidin consumption.
