Colorado State University welcomed the Dean of the Colorado School of Public Health, Jonathan Samet, MD, MS, who visited Dr. Molly Gutilla’s SAS Database Design and Management class this week. He gave a talk on using evidence to make decisions and shared some history of data creating evidence – from “little” data to “big” data. Dean Samet is a a pulmonary physician and epidemiologist, and his research focuses on the health risks of inhaled pollutants—particles and ozone in outdoor air and indoor pollutants including secondhand smoke and radon. He has also investigated the occurrence and causes of cancer and respiratory diseases, emphasizing the risks of active and passive smoking.
