Marta Guasch-Ferre

Research Scientist

Department of Nutrition


Dr. Guasch-Ferré is a Research Scientist at the Department of Nutrition at Harvard T.H. Chan School of Public Health (US) and Instructor in Medicine at Harvard Medical School and Brigham and Women’s Hospital. She holds a PhD in Nutritional Epidemiology. Her research interests include the role of Mediterranean diet on type 2 diabetes and cardiovascular disease. She is currently working on Dietary Interventions, metabolomics, type 2 diabetes and cardiovascular disease in the context of the PREDIMED Study (a randomized clinical trial for primary prevention of cardiovascular disease). She has incorporated high-throughput –omics techniques, metabolomics and genetics, into traditional epidemiological analysis to gain insights into underlying mechanisms that could explain the associations between diet and lifestyle factors in relation to type 2 diabetes and cardiovascular diseases (CVD).Dr. Guasch-Ferré research is also focused on evaluating the effect of olive oil, nuts and other dietary fats on type 2 diabetes and cardiovascular disease in Mediterranean populations (the PREDIMED Study) but also in non-Mediterranean large cohorts (Nurses’ Health Study I and II and Health Professionals Follow-up Study).

During her doctoral training, she evaluated the role of key components of the Mediterranean diet, nuts and olive oil, on metabolic syndrome, cardiovascular risk factors, cardiovascular disease and mortality in individuals at high cardiovascular risk from the PREDIMED Study. Dr. Guasch-Ferré has participated in the design, logistics, dietary interventions, data management, statistical analysis and manuscript preparation of several clinical trials, including the PREDIMED Study (more than 7,000 participants were randomized to three different interventions).
