Mission Statement

The Division of Pediatric Endocrinology, Diabetes, and Metabolism provides state-of-the-art care to infants, children, adolescents, and young adults with endocrine disorders and diabetes through NewYork-Presbyterian/Morgan Stanley Children's Hospital and the Naomi Berrie Diabetes Center.

We are committed to producing the next generation of thoughtful leaders in the pediatric endocrinology community by offering an exciting, in-depth, and high-quality experience for our fellows. Our training program combines excellent teaching and mentoring, exceptional research, and personal guidance to allow each fellow to become a skilled pediatric endocrinologist, scholarly thinker, critical investigator, and potential leader in the field.



Endocrine Activities

Every year the division has almost 8,000 outpatient visits, more than 250 in-house consultations, and 150 diagnostic endocrine tests. Fellows gain extensive clinical experience through their continuity clinic, management of both in- and outpatients, and coverage for emergencies. We are a designated site for the NY State Congenital Adrenal Hyperplasia and Newborn Thyroid Screening Program. Fellows manage the newborn screen referrals and discuss treatment planning with the supervising faculty. In 2013 we established the only pediatric DXA unit in NYC, and fellows oversee the 115 or so scans we perform annually. In 2016 we established NYC's only pediatric thyroid center in collaboration with pediatric surgery and oncology, and  adult endocrinology, and fellows care for the approximately 150 patients with thyroid conditions that we now see yearly. 

Diabetes Activities

The Berrie Center is the only multi-disciplinary diabetes center in New York City, with a large and growing referral base and a staff and patient population interested in type 1 diabetes research. Through the clinical program at the Berrie Center, which cares for 3,000 children and adolescents, fellows help manage patients with new-onset type 1 diabetes. Faculty in the division also see approximately 130 inpatients yearly who have post-transplant diabetes, cystic fibrosis related diabetes, and rare forms of neonatal and genetic diabetes.


There is a critical shortage of investigators in pediatric diabetes/obesity, and our goal is to develop and train physician-scientists in all fields of pediatric endocrinology. Current research in our division includes the study of:

  • disordered growth and pubertal development including polycystic ovary syndrome
  • the impact of environmental disruptors on obesity and pubertal development
  • obesity-related metabolic disorders
  • the genetic foundations of endocrine disorders
  • bone and body composition in childhood and adolescence
  • the pathophysiology and new therapies including immune modulation treatment of type 1 diabetes.

Graduates of the program have advanced into a variety of impressive careers. Of the 22 physicians who have graduated from the program in the last 14 years, all are board-certified, 94 percent are in research and academic-related careers, and a fifth are currently involved in intensive research. Over a third of graduates have participated in NIH-funded studies since completing their fellowship.


The overarching goal of our fellowship program is to educate and train physician-scientists, through exposure to both clinical and research-based endocrinology, to become experts and leaders in the field. All fellows complete a clinical year during which they oversee the inpatient and outpatient endocrinology services and the newborn screening program. During this year they receive intensive training in all aspects of endocrinology in a diverse quaternary care medical center. The wide and unusual range of endocrinological disorders seen at our medical center, and the experience and enthusiasm of our faculty, lead to unparalleled clinical training in endocrinology. Our fellows also must complete two research years dedicated to a project in their area of interest. Fellows select a mentor with whom they formulate a research plan. The fellows have the advantage of access to multiple university-based educational activities that may enhance their research activities.

The fellowship training program was started in 1998 and is fully accredited by the ACGME. Our fellows graduate with high-level skills and experience, and secure positions in top academic institutions throughout the United States.

Why Columbia?

Fellows have the opportunity to participate in state-of-the-art patient care and high-quality research training funded, in part, by a T32 National Institutes of Health (NIH) Pediatric Endocrine Training Grant. Fellows also have access to cross-disciplinary collaborations with research programs throughout CUIMC such as the Naomi Berrie Diabetes Center (NBDC), the Comprehensive Adolescent Bariatric Surgery Program (CABS), Columbia Center for Children’s Environmental Health (CCCEH), the Irving Institute for Clinical and Translational Research/Biomarker Core Laboratory, the Diabetes and Endocrinology Research Center (DRC), the Division of Molecular Genetics, and the CUIMC Institute of Human Nutrition. Formal coursework options include a competitive NIH-funded six-week research module for intensive training in clinical and epidemiological research.


Residents are employees of NewYork-Presbyterian Hospital and affiliated with Columbia University Irving Medical Center. With these affiliations come many benefits!
