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 mechanisms controlling nutrient or phytochemical metabolism, defining diet-disease relationships, and understanding the basis for food selection. These researchers conduct translational research that extends the more basic research. They utilize human subjects and animal models and depend upon the sciences of physiology and biochemistry. This work is often directly applicable in clinical practice or in public health.
