Dr. P. K. Newby has over fifteen years of experience researching diet, obesity, and chronic diseases; studying how people eat; and educating students and the public about a wide range of issues in food and nutrition. Weaving together traditional nutrition science, behavioral science, and environmental science, she teaches using a nutrition ecology paradigm highlighting key topics in food production and public health from farm to fork. She speaks on issues including diet and disease prevention, obesity, and the use of food technologies such as genetic engineering. She has held faculty appointments at the Schools of Medicine and Public Health at Boston University and Tufts University and is currently writing three books.
A serious cook and foodie, and an actor by avocation, Newby brings together her passions for art and science, cooking and performing, on her blog The Nutrition Doctor is In the Kitchen: Where Science is Sexy and Healthy Eating is Spectacular. Her goal is to bring sound science and fabulous cooking to people's plates through writing, television, and other media to help consumers answer the perennial question: What should I make for dinner?
Newby has an ScD in nutrition from the Harvard School of Public Health. Her master's degrees in public health and in human nutrition are from Columbia University, where she created an interdisciplinary program in health promotion and disease prevention focused on sociological, psychological, and environmental factors influencing eating behavior. She received her bachelor's degree in social welfare from the State University of New York at Albany, with minors in psychology and sociology. Her multidisciplinary training, which spans the biological, social, and public health sciences, provides her with a unique perspective when thinking about today's nutrition problems and their potential solutions.
