Dariush earned many degrees from schools all over the country, including a BS in Biological Sciences from Stanford University, an MD from the Columbia College of Physicians and Surgeons, an MPH from the University of Washington School of Public Health, and a DrPH in Epidemiology from the Harvard School of Public Health. His research interests include: effects of omega-3 and trans fatty acids on cardiovascular outcomes, intermediary phenotypes, and metabolic and physiologic pathways; policy issues related to fat consumption in developed and developing nations; quantitative analyses of risks and benefits of fish consumption; global cardiovascular health; and the combined impact of multiple dietary and other lifestyle behaviors on cardiovascular and metabolic risk. His studies suggest that eating fish several times a week dramatically decreases the risk of heart attacks.
