Exercise and Nutrition Sciences



Studying how we move and fuel our bodies.





Diet. Exercise. Everyone knows those are the basic pillars of good health, but establishing a healthy lifestyle is much more complex than “eat better, move more.” Students in the Department of Exercise and Nutrition delve into those complexities and examine the link between physical activity and nutrition and the wellbeing of an individual and their community. They then use that information to develop in-depth and detailed interventions that can help people live happier, healthier lives.

Our Bachelor of Science (BS) programs deliver a versatile background in topics such as physiology, psychology, nutrition and exercise science. Our master's degree students learn the more advanced science behind exercise performance, physical activity promotion, and nutrition science, as well as how to design programs that promote health and wellness at the individual, as well as at the population level.

Cate Alvaro

Research Keeps it FRESH for Exercise Science Major

Senior exercise science major Cate Alvaro ‘23 remembers the moment she was sold on the Milken Institute School of Public Health for her undergraduate degree. “When I toured campus, they brought us into Milken and down into the exercise and nutrition science labs. We were able to see all the different equipment and how they were using it for a variety of research studies. I remember being really excited about that and wanting to get involved in research.”
