Graduate Courses |

(Interdepartmental Graduate Major)

Advisory Committee: Kevin Schalinske, Chair; Don Beitz, Manju Reddy, Chad Stahl, Wendy White

Participating Faculty: Faculty from Food Science and Human Nutrition, and Animal Science as well as other departments such as Health & Human Performance; Biochemistry, Biophysics, and Molecular Biology; Agronomy; Human Development and Family Studies; Economics; Sociology; and Statistics.

Graduate Study

The Interdepartmental Graduate Program in Nutritional Sciences (IGPNS), administered through the Graduate College, under the auspices of the Chairs of Food Science and Human Nutrition (FS HN) and Animal Science, will provide the structure for coordinating and enhancing interdisciplinary nutrition research and graduate education. M.S. and Ph.D. degrees in Nutritional Sciences will be offered with four specializations: Animal Nutrition, Human Nutrition, Global Nutrition, or Molecular/Cellular Nutrition.

The following undergraduate course work is recommended of all applicants who are applying to the IGPNS, but may be modified depending upon the student's area of emphasis. Recommended course work includes organic chemistry with laboratory, physics, analytical chemistry, a nutrition course that requires biochemistry or organic chemistry as a prerequisite, and a course in biology/physiology or anatomy. Under certain circumstances students can be admitted or provisionally admitted with course work deficiencies. Students with an undergraduate degree will be generally admitted into the M.S. program and upon completion, they can then apply for admission into the Ph.D. program. However, exceptional students with experience can apply directly to the Ph.D. program.

The general requirements of the Nutritional Sciences degree at the M.S. level, in addition to those of the Graduate College, are: NutrS 501; NutrS 502; a minimum of 2 additional credits of graduate-level advanced nutrition or nutritional physiology; 3-6 credits of graduate-level biochemistry; 3 credits of graduate-level statistics; seminar(s) attendance in Food Science and Human Nutrition (FS HN 681) or Animal Science (An S 603); graduate student orientation course (FS HN 580 or An S 501); a seminar presentation course (FS HN 581 or An S 603); one semester credit of seminar pertaining to student's research; and successful completion of a thesis and defense of the thesis. Graduate students are expected to complete the course work established by the Program of Study (POS) committee based on the area of specialization with a minimum of 30 graduate-level semester credits, not less than 22 of which must be earned at Iowa State University.

The general requirements of the Nutritonal Sciences degree at the Ph.D. level, in addition to those of the Graduate College, are: completion of all requirements of the M.S. degree in Nutritional Sciences; 3 additional graduate level credits in each, biochemistry (if only 3 credits are taken for M.S.), statistics, and physiology; and 6 additional advanced graduate courses to be determined by the POS committee based on the area of specialization. Satisfactory completion of a preliminary examination, a written dissertation, seminar presentation of dissertation research, and defense of the dissertation is also required. Overall a minimum of 72 graduate-level semester credits are required for the Ph.D. degree and not less than 36 of the credits must be earned at Iowa State University.
