Department of Nutritional Sciences

Welcome to the Department of Nutritional Sciences

The faculty and staff of the Nutritional Sciences Department are committed to excellence in undergraduate and graduate education, research, and extension.  We offer a comprehensive educational experience for undergraduate and graduate students who are interested in promoting the health and wellness of individuals as well as communities through the prevention and treatment of disease. Graduates are prepared for careers in dietetics, nutrition, and an array of areas within the biomedical field. Nutrition professionals work in a wide range of settings, in both the public and private sector. 

Undergraduate options are tailored to prepare our students for their ultimate professional goals.  Students in the Dietetics option complete the ACEND-accredited coursework required to apply to ACEND-accredited Dietetic Internships and take the Registered Dietitian (RD) exam. Human Nutrition-Premedical Science and Allied Health option students complete prerequisite courses needed to apply to a wide variety of healthcare professional programs or graduate school. Students in the Community Nutrition option complete courses which prepare them to pursue careers in non-therapeutic food and nutrition fields. Pursuit of graduate education resulting in a master’s or doctoral degree is also an option for successful undergraduate students.

Our graduate faculty advance the science and application of nutritional science through basic cellular and molecular, translational, and community research. The impact of their work is seen throughout the state of Oklahoma, the nation, and the world. Working with master’s degree and doctoral students, they are preparing the next generation of nutritional scientists. Our dietetic interns earn master’s degrees before completing their rotations.  Faculty members working with the Oklahoma Cooperative Extension Services affect the lives of individual Oklahomans for the better by applying research findings to real-life settings in homes, schools, and businesses.
