Dean Ornish, MD

Dr. Ornish is a Clinical Professor of Medicine at UCSF and the founder and President of the Preventive Medicine Research Institute. His pioneering research was the first to prove that lifestyle changes may stop or even reverse the progression of heart disease and early-stage prostate cancer and even change gene expression, “turning on” disease-preventing genes and “turning off” genes that promote cancer, heart disease and premature aging. Recently, Medicare agreed to provide coverage for his program, the first time that Medicare has covered an integrative medicine program.

He is the author of six bestselling books and was appointed by President Obama to the White House Advisory Group on Prevention, Health Promotion, and Integrative and Public Health. The Ornish diet was rated #1 for heart health by U.S. News & World Report in 2011 and 2012. He was selected as one of the “TIME 100” in integrative medicine, honored as “one of the 125 most extraordinary University of Texas alumni in the past 125 years,” recognized by LIFE as “one of the 50 most influential members of his generation” and by Forbes as “one of the 7 most powerful teachers in the world.”

Gianni Pes, MD, PhD

Dr. Pes is a Senior Researcher in the Department of Clinical and Experimental Medicine at the University of Sassari, Italy. He graduated in Medicine and received a PhD in Medical Statistics from the University of Pavia, Italy. He started to study Sardinian longevity in 1996 and was the first to report in 1999 on the exceptional longevity of the population living in the mountains of Sardinia. The region was later determined to be one of the original Blue Zones regions.

Since 2000, he has been working in collaboration with the demographer Professor Michel Poulain of the Université catholique de Louvain in Belgium. His work focuses on nutritional and lifestyle factors associated with a long life. Dr. Pes has published more than 100 scientific articles in peer-reviewed journals, and is co-author with Professor Poulain of the book Longevity and Identity in Sardinia.

Michel Poulain, PhD

Dr. Michel Poulain is a Senior Researcher at the Estonian Institute for Population Studies at Tallinn University in Estonia. He earned his PhD in demography from Université catholique de Louvain in Belgium, where he currently serves as Emeritus Professor.

Since 1999, Dr. Poulain has studied supercentenarians (people reaching extreme old ages) for the International Database on Longevity. Among his findings, Michel discovered that centenarians in Sardinia were not randomly distributed on the island; instead they were concentrated in an area that he named a ‘Blue Zone’. From there he began a quest to validate age and centenarians worldwide.

In 2005, he began working with Dan Buettner to identify other “Blue Zones” such as Nicoya (Costa Rica) and Ikaria (Greece). Since 2004, he has worked in collaboration with Dr. Gianni Pes of Sassari University to publish scientific papers summarizing the characteristics of four out of the five Blue Zones identified to date. His research focuses primarily on longevity determinants with special emphasis on demographic, socio-cultural and anthropological perspectives.

Dr. Willett studies the effects of diet on the occurrence of major diseases. He has developed specific methods to study this topic and applied them to 300,000 men and women starting in 1980 in the Nurses’ Health Studies I and II and the Health Professionals Follow‐up Study providing the most detailed information on the long‐term health consequences of food choices.
