Administration
At the Institute of Human Nutrition (IHN), our administrative team supports the delivery of educational programs that deepen knowledge in clinical, public health, and basic science nutrition. We collaborate with faculty, researchers, and students to foster partnerships—both nationally and internationally—with universities and institutions that share our mission.
As part of Columbia University Medical Center, we are committed to cultivating a welcoming and supportive learning environment for graduate students. Our team aims to be helpful, resourceful, knowledgeable, and efficient in all interactions.
Working collaboratively, we ensure the smooth operation of IHN’s academic programs. Guided by our core values and a spirit of flexibility, we contribute to the growth and success of our students, staff, and faculty—and to the advancement of the IHN as a whole.
