Endocrinology Fellowship

About the Fellowship

The fellowship is a three-year program intended to prepare fellows for a career in academic pediatric endocrinology. The program combines clinical endocrinology and diabetes care with excellent opportunities for clinical and laboratory-based research within the division and through close liaisons within the Department of Pediatrics at Children's Hospital Los Angeles, The Saban Research Institute and the Keck School of Medicine at the University of Southern California. The program has a rich history of excellence in endocrinology and diabetes extending back almost 30 years. 

Learn More About the Program

The Center for Endocrinology, Diabetes & Metabolism has been named one of the top seven programs in the country by U.S. News and World Report for the last five years in a row. With nine full-time and six part-time attending physicians, as well as seven diabetes nurse educators, the fellows are exposed to a wealth of expertise in various aspects of pediatric endocrinology. In addition, fellows have the opportunity to interact with other highly regarded and productive divisions in the hospital that care for patients with diverse pediatric issues. It is the intent of the program that fellows will be well-trained in diagnosis and management of endocrine disorders of childhood, be able to teach and lecture on endocrinology and diabetes, and be familiar with the methodology and techniques of routine endocrine laboratory studies. Another critical component of the fellowship is to be able to design and carry out clinical and laboratory investigations.

The fellow will spend 12 months during the fellowship as the "on-service fellow." The service time is generally allocated as follows:

  • six months in year one
  • four months in year two
  • two months in year three

On-service fellows will manage the inpatient endocrine and diabetes service, under the supervision of attending faculty. They will round with pediatric residents and see all consults and primary endocrine and diabetes patients. On-service fellows will also see urgent outpatient consultations, and triage urgent patient phone calls.

When off service, fellows will attend two clinics per week including their own continuity clinic. The continuity clinic will carry on through all 3 years of fellowship and will be staffed by a dedicated attending physician. Non-continuity teaching clinics are preceded by a one-hour conference with the attending, which is spent discussing cases to be seen and endocrine/diabetes topics of interest. Incorporated in teaching clinic schedule are our multidisciplinary clinics including Comprehensive CAH and hyperandrogenism clinic, Turner syndrome clinic, EMPOWER weight management clinic, Type 2 diabetes clinic, Neuro-oncology Clinic, and Thyroid nodule clinic.  In addition, fellows have the opportunity to do rotations in other CHLA divisions, including but not limited to Lipid clinic (Cardiology), Transgender clinic (Adolescent Medicine) and Genetics clinic.

Fellows engage in research throughout their training (for a total of 22 months while "off service"). In their first year, fellows will choose their research project and mentors, in coordination with the fellowship director. They will lay the groundwork for their project(s), and choose their Scholarship Oversight Committee, which will monitor their scholarly progress throughout their fellowship. During the second and third years, fellows will focus primarily on their research project(s). Clinical research projects are expected to be hypothesis-driven and rigorously performed. Bench research should involve a discrete project in which the fellow does the majority of the hands-on work. Both types of research should lead to one or more first-authored publications for the fellow. Fellows are encouraged to attend and present their research at institutional, local, and national scientific meetings, and the division provides clinical coverage and financial support for these activities. Fellows are required to apply for at least one grant during their fellowship.

Endocrinology fellows have the opportunity to participate in a wide variety of clinical and laboratory-based research projects. Fellows develop their own projects, building on one of a number of ongoing projects within the division, or with one of several collaborators in other divisions at Children’s Hospital Los Angeles or in the Keck School of Medicine of the University of Southern California.

Fellows cover the service on weeknights and weekends all 3 years, in rotation with one another, resulting in being “on call” weeknights and weekends for one in every five or six nights/weekends. Call is primarily from home, though weekend call involves morning inpatient rounds, and fellows are expected to be available to come into the hospital for rare emergencies.

Fellows have access to a variety of educational experiences during their fellowship, including, but not limited to:

  • Thursday morning divisional educational conference (invited speakers, case presentations, journal club)
  • Endocrine brown bag lecture series (monthly)
  • Pediatric endocrinology board review (monthly)
  • Research meetings with Fellowship Director (monthly)
  • Fellows’ core curriculum (covers general education, research and professionalism for all Children’s Hospital Los Angeles subspecialty fellows)
  • Responsible conduct of research
  • Bone conference
  • Endo-Urology, Endo-Radiology, and Endo-Genetics joint conferences
  • Clinical & Translational Research Study Design Course (8 weeks long)
  • Divisional research updates
  • Diabetes camp
  • Pediatric grand rounds
  • The Saban Research Institute chalk talks
  • Patient education conference participation, e.g., the annual meeting of the MAGIC Foundation
  • Access to graduate courses and masters programs at USC with tuition remission
  • "Pre-tending" Week
