The Interdepartmental Nutrition Graduate Program (INP) is an interdisciplinary training program for students interested in the study of nutrition science. Faculty from several departments provide a wide range of expertise and training opportunities. Students interested in participating in INP apply to the Purdue West Lafayette (PWL) - Nutrition Science graduate program. Admitted students train under an INP faculty mentor to earn either a Master of Science or Doctor of Philosophy degree. Students learn a variety of approaches to address important nutrition issues. Students and faculty in this training group examine the role of nutrition in promoting the optimal growth and development of production animals or in improving the health of production and companion animals. These researchers utilize animals in their studies and depend upon the sciences of physiology and biochemistry. This work is often directly applicable to the field or in clinical veterinary practice.
