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 three specializations: Animal Nutrition, Human Nutrition, or Molecular/Biochemical 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 MS level, in addition to those of Graduate College, are: NutrS 501; NutrS 502; a minimum of 4 additional credits of graduate-level advanced nutrition or nutritional physiology; 3-6 credits of graduate-level biochemistry; 3 credits of graduate-level statistics (STAT 401); graduate student orientation course (FS HN 580 or An S 501); seminar(s) attendance in Food Science and Human Nutrition (FS HN 581) or Animal Science (An S 603); seminar presentation course (FSHN 681 or An S equivalent); one semester credit of seminar pertaining to student's research; Teaching assistant requirement (FS HN 590C or AnS 590L), summer lectureship (NutrS 505) and successful completion of a thesis and defense of the thesis. They are expected to complete the course work established by the Program of Study (POS) committee based on 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 Nutritional Sciences degree at the PhD level, in addition to those of the Graduate College, are: completion of all requirements of the MS degree in Nutritional Sciences; 3 additional credits in each of graduate-level biochemistry, graduate-level statistics (Stat 402), and systemic physiology; and one additional graduate-level courses in the field of study as deemed appropriate by the POS Committee and additional teaching assistant requirements (FS HN 590C or An S 690L). 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, no less than 36 of which must be earned at Iowa State University.
