Animal and Nutritional Science (ANSC)

https://colsa.unh.edu/anfs/animal-and-nutritional-sciences

Degree Offered: Ph.D.

This program is offered in Durham.

The Department of Agriculture, Nutrition, and Food Systems offers the Ph.D. in animal and nutritional sciences. The Ph.D. degree in animal and nutritional sciences has, as its primary research foci, the study of biological and nutritional processes that promote animal and human health and disease, and in the case of animal health, its effect on production. Areas of research specialization include human nutrition, mammalian physiology and pathology, nutritional biochemistry and metabolism, and reproduction and endocrinology. Research activities utilize human, animal, and cell culture systems to investigate nutrient metabolism and a molecular-­level understanding of life processes and diseases.

Admission Requirements

Students applying for the Ph.D. program will be expected to present recent (within five years) general Graduate Record Examination (GRE) scores and possess a background in basic sciences appropriate for advanced study in the proposed area of specialization (for example, courses in biology, chemistry, organic chemistry, biochemistry, and physics). Although not required for candidacy in the Ph.D. program, an M.S. degree is suggested for most students. The student's committee may require certain undergraduate courses as part of the graduate program if additional competencies would be beneficial to the student.
