Nutrition and Metabolism PhD Program
Nutrition researchers are a critical part of our society as they examine the complex interplay between nutrients, health, and disease, spanning from the individual to populations. With careers as faculty or independent scientists in academia, industry, and government, graduates of the Nutrition and Metabolism (N&M) PhD Program are at the forefront of research. They are making important contributions linking diet to the maintenance of health and impact on disease prevalence, and educating the public on the critical role of diet in the maintenance of optimal health throughout the life cycle.
Research
52 faculty trainers across 17 departments provide extensive interdisciplinary training opportunities in molecular, human and animal nutrition research.
Program Requirements
Our flexible curriculum provides core nutrition and metabolism coursework, with ample opportunities for elective coursework and minors.
Student Life
Gain a world-class education in a world-class city. Madison is a vibrant and inclusive community, and is consistently ranked as one of the best places to live in the U.S. for quality of life.
“Whether you’re driven by discovery, problem-solving, or the pursuit of knowledge, we look forward to helping you shape your research journey and make meaningful contributions to your field.“
-Dr. Rick Eisenstein, Director of Graduate Studies
