Training for fellows in pediatric endocrinology involves intensive clinical training in all aspects of clinical pediatric endocrinology. The large volume and broad range of endocrine pathology seen by Children’s Hospital endocrinologists ensures an optimal clinical experience for endocrine fellows.
The first year of the Pediatric Endocrinology Fellowship consists of clinical training and incorporates some preparation for the second year, while the second and third year consist mainly of research with some clinical training (continuity clinics, inpatient consultation). During year one of the clinical track you will identify an area of research interest and a mentor for pursuit during the second year.
All fellows are directly supervised by faculty members (CHCO, UCH, or BDC) specific to that rotation and by the inpatient consult attending for the inpatient consultation rotation. This attending physician shall be available at all times to the endocrine fellow. It is the responsibility of the fellow to communicate effectively and in a timely fashion with the attending physician as well as other members of the Endocrine Faculty. At each stage of training, the goal is to provide a level of supervision that ensures patient safety and maximizes education while promoting the trainee’s sense of independence and autonomy
Call for pediatric endocrine fellows are at home call. They are required to answer phone calls from parents of patients, outpatient phone consults and inpatient consult service. They rarely have to go into the hospital for an urgent consult. Pediatric endocrinology fellows take call up to 5 days per month, and weekends are divided throughout the fellowship.
Fellows are expected to attend the following educational conferences (roughly 1-2 per week) during the fellowship program:
Note: All conferences offer an in-person and virtual format to accommodate our team members' clinic and call schedules.
Fellows Academic Half Day: Second Thursday per month, 1-5 pm
Conference includes pediatric endocrinology fellows, program director/associate program director, and other endocrine and diabetes faculty members. This conference includes our board review course (Fundamentals of endocrinology), clinical guideline review, review of cases with experts and training in research methods as well as methods for wellness and resiliency. During Fellows' Academic Half Day, all fellows are free from patient care responsibilities.
Pediatric Endocrine Case Conference: Second Monday and Fourth Tuesday per month, 11 am - 1 pm
Conference includes pediatric endocrinology fellows, pediatric endocrine faculty, staff (including but not limited to our amazing Pharmacy, Nursing and and Lab Teams). Cases are brought by both fellows and faculty for discussion and review. Fellows present a more formal case with a detailed literature search 6 times per year during their first year. This is also the forum for discussion of topics related to the laboratory or pharmacy.
In addition, Journal club is a component of this conference. Second- and third-year fellows present 2-3 times per year. Journals are reviewed by the presenter to identify articles that are pertinent to pediatric endocrinology and diabetes. Reviewers select 3-5 articles for detailed discussion. Fellows are encouraged to select 2-3 articles for more in depth discussion of study design, statistics, and interpretation of results. This facilitates skill in critical reading of the literature, analysis of study design, statistics, extrapolation of research studies to clinical care of children with diabetes and other endocrine problems.
Another unique component of this conference is that we use this conference time to schedule quarterly joint BDC and Endocrine Meeting of the Minds, professional development and leadership trainings.
Diabetes Conference: Tuesdays, 12-1 pm
Conference includes pediatric endocrine fellows and pediatric diabetes faculty. Endocrine fellows present in the conference annually. Topics include research in progress, clinical topics related to diabetes care, instruction on effective reading of the literature, and much more.
Endocrine Grand Rounds: Wednesdays, 8-9 am
Conference includes pediatric endocrine fellows and pediatric endocrine faculty, endocrine fellows, and faculty. Endocrine fellows present once as a first-year fellow. Topics include challenging endocrine cases, updates to clinical practice of endocrinology, invited speakers from across the country, etc..
Pediatric Endocrine Summer School Lecture Series: July-August, Dates and times vary
Conference consists of varied topics pertinent to the clinical care of children with diabetes and other endocrine problems. Presenters are faculty in the division of pediatric endocrinology and the Barbara Davis Center. The purpose is to provide a broad overview of the general topics of pediatric endocrinology and diabetes and provide the fellows with a foundation for the clinical care of children with these disorders.
Quarterly Endocrine Meeting: Every 3 months, Monday, 8 am-12 pm
Endocrine and diabetes faculty and fellows attend this conference. Conference includes an hour of didactic lectures from disciplines throughout the University (radiology, urology, genetics, reproductive endocrinology, etc.), time for morbidity and mortality. Conference includes an hour for the discussion of disorders of sexual differentiation in a multi-disciplinary team.
Department of Pediatrics Conferences
While these conferences are not required for fellows to attend, our fellows are encouraged to explore and attend ones that interest them. Some of our Pediatric Endocrinology Fellow Alumni become guest speakers at these conferences!
Department of Pediatrics and Other Research Conferences
There are multiple research focused conferences throughout the Anschutz Medical Campus, including at Children’s Hospital and the Barbara Davis Center. All research conferences are shared with the fellows as optional learning opportunities.
The University of Colorado Anschutz Medical Campus (CU Anschutz) is the largest academic health center in the Rocky Mountain region which brings together on the same campus three major hospitals and educational, administrative, and research facilities for all six health science schools of the University of Colorado. The 11.3 million ft2 of state-of-the-art facilities has benefited from over $4 billion of investments to date. The 230-acre campus provides adjacencies of clinical, educational, and research facilities all within walking distance of each other, building a new culture of collaboration among clinicians, investigators, and educators that invigorates research and innovation. An adjacent biotechnology park helps facilitate close collaboration between University investigators, industry, and the private sector.

The Department of Pediatrics is a national and international leader in child health research. Our research program consistently ranks among the top three departments of pediatrics nationwide in NIH research funding. Our faculty are active leaders of research initiatives spanning the full range of basic and clinical investigations, ensuring that discoveries made in the laboratory will be translated into tomorrow’s cures.
Much of our research is organized into highly collaborative centers and institutes supported by state-of-the-art facilities that bring diverse expertise and perspectives to bear on challenging aspects of child health. Our faculty are also passionate teachers training students and fellows to become tomorrow’s research leaders.
Learn more about the Department of Pediatrics research milestones, NIH research funding, and recent faculty publications.
The Barbara Davis Center (BDC) is a consistent incubator for novel ideas and discoveries in the immunology, genetics, and cell biology of diabetes that have developed into diagnostic assays now standard in diabetes research. The BDC research goals include investigation of the causes of type 1 diabetes, the early detection of autoimmunity, prevention and early intervention. In addition we are developing new treatments, including a focus on the artificial pancreas, and prevention strategies for complications of both type 1 and type 2 diabetes, and the outcomes of care of type 1 diabetes.

Also, learn about the University of Colorado Denver Diabetes Research Center (DRC) here.
In addition to the SOC mentors, our pediatric endocrinology fellows are partnered with an Endocrine or Diabetes faculty with a research focus at the start of the fellowship. Fellows work with both their SOC and faculty mentors throughout their fellowship to learn and gain valuable research training and mentorship while working on their research project.
In addition, research experts from our faculty team at CHCO, the BDC and CU Anschutz are invited to the monthly Fellows' Academic Half Day Conference for research-related lectures and trainings (for example, topics include research methods/study designs, methodology, patient safety and quality improvement, etc.).
Fellows are also invited to weekly, optional research office hours (in-person/virtual), hosted by one of our expert peds endo research faculty.

First Year Fellows:
Currently, the first-year fellows are recruiting their SOC mentors.
Research is an important component of the pediatric endocrinology fellowship program. Training in research methods begins in the first year. The goal is to provide trainees with an intensive introduction to the principles and techniques of clinical and/or laboratory investigation.
In the first year of fellowship, fellows have 1-2 months dedicated to research to allow for the identification of a mentor and a project. Fellows will then prepare a research proposal with the guidance of the mentor.
With the guidance of the fellowship program director and research director, fellows will select a Scholarly Oversight Committee (SOC) in the second half of the first year of fellowship to help oversee the research training period.
The SOC is composed of at least 3 faculty members who:
Requirements for the SOC include one pediatric endocrine faculty member, another endocrine faculty member (either pediatric or adult) and a member outside of the divisions of pediatric and adult endocrinology. Additional SOC members may be recruited as needed by the fellow.
During the second and third year of fellowship, fellows are expected to spend around 75-80% of their time working on research projects under the direction and guidance of the fellow’s primary mentor(s).
We require fellows to complete a scholarly work product by the end of the pediatric endocrinology fellowship. While the minimal requirement of success is preparation of a scholarly research proposal, the SOC will regularly assess progress towards completion of experimental studies, submission of abstracts to national meetings, presentations of posters or oral presentations at national meetings, submission and publication of study results, and the submission of grant applications. Members of the SOC are also required to sign-off on the scholarly work and personal statement submitted to the American Board of Pediatrics for board eligibility.
